Replace tab-load-only injection with scripting.registerContentScripts()
so custom domains inject at document_start (like built-in sites) and
persist across service worker restarts. Scripts re-register automatically
when domains change. Removed domains now revoke browser permissions.
https://claude.ai/code/session_01KF4i7Ra7zCEDskxDBaNtcT
Sync operations (browser sync, Gist, custom URL, sync code) now refuse to
operate without encryption enabled. Disabling encryption also turns off all
active sync channels. Activity log cap reduced from 200 to 100 entries for
both storage and display.
https://claude.ai/code/session_01KF4i7Ra7zCEDskxDBaNtcT
Auto-sync now:
- Persists Gist token in the auto-sync config so it survives
page reloads (previously only read from the input field)
- Saves token when the Gist token field changes (not just on toggle)
- Validates that credentials exist before enabling
- Shows current status: method, interval, last push/pull times
- Updated UI description to clarify it works in all browsers
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
_getAllData() was reading raw storage which contains encrypted blobs
when at-rest encryption is enabled. The sync code export would send
{ _ssLocalEncrypted: true, data: <blob> } instead of actual identity
data. The importing browser couldn't use these blobs.
Fixed _getAllData() to use Storage._readSecure() which decrypts
transparently. Fixed _applyData() to use Storage._writeSecure()
so imported data gets encrypted on the receiving end.
Also: hide the Auto-Sync Folder section entirely in browsers that
don't support File System Access API (Firefox, Brave, Safari)
instead of showing a broken-looking error message.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Fixed safeHTML in all three files — template.content.childNodes and
doc.body.childNodes are live NodeLists that shrink as nodes are moved.
Using Array.from() to create a static copy before spreading into
replaceChildren().
Expanded proper noun common words filter with ~500 additional verbs,
nouns, and adjectives (generate, design, manage, process, account,
button, dashboard, etc.) to prevent false PPI flags on titles,
headings, and UI button labels.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Replaced all 31 innerHTML assignments across popup.js (12),
options.js (17), and content.js (3) to pass Mozilla AMO linter.
Each file gets a safeHTML(el, html) helper:
- popup.js/options.js: DOMParser-based (extension page context)
- content.js: <template> element pattern (page world context)
Empty innerHTML clears replaced with el.replaceChildren().
innerHTML += replaced with createElement + safeHTML + appendChild.
All event listener bindings after HTML rebuilds remain functional
since safeHTML uses replaceChildren() which populates DOM
synchronously before querySelectorAll + addEventListener calls.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Passwords imported from password managers are now:
- Displayed as dots (••••••••) by default in both options and popup
- Separated into their own "Passwords" section in options page
- Only revealable by entering the vault encryption password
- Always masked in the popup mappings list (no reveal there)
Options page:
- New Passwords section with locked/unlocked states
- Reveal button validates against vault encryption password
- Hide button re-masks all password values
- Password mappings excluded from the general Mappings table
- Delete and enable/disable controls work while masked
Popup:
- Password-category mappings show dots for real value
- Password category added to mapping add form dropdown
Storage:
- Added 'password' to default categories list
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
New module: import-parser.js
- Auto-detects format from filename and content headers
- Chrome/Firefox password CSV: extracts usernames, emails, domains
(NEVER imports passwords)
- Bitwarden/1Password CSV: extracts usernames, emails, domains
- Browser autofill CSV: extracts names, emails, phones, addresses
- Plain CSV: two-column real→substitute with optional category
- Plain text: one value per line, auto-categorizes (email, phone, name)
- Values without substitutes are marked "needs mapping" so the user
can see what needs filling in
Options UI:
- Import button in Transfer Data section
- Preview panel shows parsed items before applying
- Summary shows counts and highlights items needing substitutes
- Apply merges into active profile (identity) and mappings table
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
All sensitive data (identity, mappings, activity log) is now AES-256
encrypted in browser.storage.local when sync encryption is enabled.
TOTP secret is also encrypted at rest using the derived key.
Vault unlock flow:
- On browser restart, extension detects locked state (encrypted data,
no cached CryptoKey) and shows LOCK badge in red
- Popup shows a full-screen unlock prompt with password field,
optional TOTP, and biometric button
- After unlock, background decrypts and broadcasts data to all tabs
- Content scripts start with empty config when locked; receive
decrypted config via vault:unlocked message after unlock
- Injector skips encrypted blobs in storage change events
Storage module changes:
- _readSecure / _writeSecure transparently encrypt/decrypt
- encryptExistingData() migrates plaintext → encrypted on setup
- decryptAllData() restores plaintext when encryption is disabled
- isLocked() checks for encrypted data + missing key
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Re-verification (TTL expired, key still cached) now accepts any ONE of:
- WebAuthn (biometric/PIN)
- TOTP code alone (no password needed)
- Password alone (no TOTP needed)
First-device setup still requires password (+ TOTP if configured) since
the password is needed to derive the encryption key.
Added reverifyWithTOTP() and reverifyWithPassword() to sync.js.
Auth prompt UI adapts: first-device shows password+TOTP fields,
re-verify shows all three methods as alternatives.
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
- CryptoKey now persists in IndexedDB forever — never auto-deleted
- TTL controls when re-verification is needed, not key lifetime
- WebAuthn is the primary re-auth method (not a post-expiry fallback)
- Password only needed once per device (first-time setup)
- Added needsReverification() and markVerified() to crypto.js
- Auth prompt adapts message: first-device vs re-verify vs decrypt
- Biometric button hidden on first-device setup (no credential yet)
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
Sync encryption:
- AES-256-GCM encryption for all sync channels (browser sync, gist,
custom URL, folder sync, sync codes)
- Password with optional TOTP (RFC 6238) second factor
- Configurable auth TTL: session, 30/90/180/365 days, or never
- CryptoKey cached in IndexedDB — auth only needed when cache expires
AND new data exists (lastModified check runs before auth prompt)
- WebAuthn (biometric/PIN) as low-friction re-authentication gate
- Full options UI for setup, password change, and inline auth prompt
Smart reveal:
- Track which substitute values were actually sent outbound per session
- Reveal mode only replaces values that were genuinely substituted,
preventing false positives (e.g. AI using the word "user" won't be
replaced with a real username that maps to "user")
https://claude.ai/code/session_01SWSwDfMVij53bCTNSCLMwn
GitHub Gist sync:
- pushToGist(token): pushes all settings to a private Gist; creates a
new Gist on first use and stores the Gist ID in local storage so
subsequent pushes update the same Gist.
- pullFromGist(token): fetches the Gist, compares lastModified, applies
if newer (raw_url used to avoid API truncation).
- No desktop client needed; works across any browser/OS with a GitHub PAT.
- Options page shows a token field + Push/Pull buttons; Gist ID shown
once linked.
Custom URL sync:
- pushToUrl({ url, method, headers }): HTTP PUT to any endpoint.
- pullFromUrl({ url, headers }): HTTP GET, applies if newer.
- Works with Nextcloud/ownCloud WebDAV, self-hosted servers, cloud
functions, or any static-file host that allows PUT.
- Options page shows URL + optional JSON headers field + Push/Pull.
Both methods write ss_sync_notification on apply, triggering the purple
'SYN' badge and desktop notification added in the previous commit.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
Notification system:
- When sync applies data (file folder, browser account, or sync code),
ss_sync_notification is written to local storage with the source.
- Service worker catches it via storage.onChanged, shows a purple 'SYN'
badge on the extension icon that persists until Options is opened, and
fires a desktop notification ('Settings updated via sync folder — open
Options to review').
- Clicking the desktop notification opens the Options page directly.
- On service worker wake, SYN badge is restored if the notification was
not yet dismissed.
- Opening Options clears ss_sync_notification, resets the badge, and
sends a sync:notification-seen message to the service worker.
- Added 'notifications' permission to both manifests.
Cloud storage clarity:
- Options page now explicitly lists that the folder sync works with any
cloud storage that has a desktop sync client: Dropbox, OneDrive, Google
Drive, iCloud Drive, Box, pCloud, Nextcloud, Synology Drive, etc.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
PPI + button fix:
- After adding a mapping, the real PPI value is now immediately replaced
with the fake value in the input/contenteditable element via the new
replaceInInput() helper (handles both <textarea>/<input> and
contenteditable divs by walking text nodes).
- Triggers a re-scan 150ms later so the pre-send warning updates or
dismisses itself if no more PPI remains.
Auto-sync folder (File System Access API):
- User picks a folder once per browser via "Choose Sync Folder".
Any settings/mappings/identity change writes silent-send-sync.json
to that folder automatically (via api.storage.onChanged listener).
- On options page open and every time the page regains focus, the file
is read back; if its lastModified is newer than local data, settings
are imported immediately and the UI refreshes.
- File handle is stored in IndexedDB (ss_sync_handles) so it persists
across browser sessions without repeated permission prompts.
- Pick the SAME folder in each browser (or a synced cloud folder for
cross-computer sync) — fully automatic after that, no copy-paste.
- sync.js gains saveSyncDirHandle / loadSyncDirHandle / clearSyncDirHandle
helpers backed by IndexedDB.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
Bug fixes:
- Date (possible DOB) pattern now requires context words (born, birthday,
dob, etc.) before firing — prevents spurious warnings on page-load API
calls that happen to contain ISO dates in conversation history.
- Highlight regex now uses word boundaries (\b) so short substitute values
(e.g. "aud") no longer match inside unrelated words like "Claude".
- Both TreeWalkers in content.js now skip the extension's own UI elements
(.ss-autodetect-warning, .ss-presend-warning, .ss-reveal-badge) to
prevent the highlight API from marking text in the extension's banners.
Settings sync:
- New src/lib/sync.js: exportSyncCode / importSyncCode (base64 JSON) for
manual copy-paste across any browser combination. Newest lastModified
timestamp wins; force flag available to override.
- browser.storage.sync support: when "Browser account sync" is enabled the
extension automatically pushes/pulls via Firefox Sync or Chrome account,
chunked to stay within per-item quota limits.
- storage.js now writes ss_lastModified on every save so conflict resolution
has an accurate timestamp.
- service-worker.js listens for both local and sync storage changes to keep
all copies in sync.
- New "Sync Between Browsers" section in options.html with Generate/Copy/
Import Sync Code UI and the browser sync toggle.
https://claude.ai/code/session_01TKpSR9M8JgHLXCp5CeDsQP
Detected PPI is now auto-redacted in the fetch hook using
RFC/standard reserved values — not just warned about:
- IPs → 192.0.2.1 (RFC 5737 TEST-NET-1, never routed)
- MACs → 00:00:00:00:00:00
- Addresses → 123 Example Street, Anytown, ST 00000
- GPS → 0.000000,0.000000 (Gulf of Guinea)
- Dates → 01/01/1970 (Unix epoch)
- EINs → 00-0000000 (impossible prefix)
- Paths → /home/user
- Git → example org
These are obviously fake and guaranteed not to be real data,
unlike random values which could be confused with actual PPI.
New Options toggle: "Auto-redact detected PPI on send" (on by
default). When on, PPI is caught in the fetch hook even if the
user hits Enter immediately after pasting. Warning banner now
says "Auto-redacted with standard placeholders" instead of
"These were sent as-is."
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Like spellcheck for privacy. Scans text as you type and paste
into chat inputs (debounced 800ms). Shows a dark floating warning
panel listing detected PPI BEFORE you hit Enter.
Each detected item has a green [+] button that instantly:
1. Generates a plausible fake value (random IP, fake address, etc.)
2. Adds it as a mapping to storage
3. Shows a checkmark to confirm
The warning disappears when you clear the text or when all
detected items have been addressed.
Three new Options toggles:
- Auto-detect unconfigured PPI (on by default)
- Offer to auto-add detected PPI (on by default)
Also adds a storage bridge (postMessage) so the page-world
content script can read/write chrome.storage through the
injector.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Scans outbound messages AFTER all substitutions for personal data
the user forgot to configure:
- Private/public IP addresses (skips 127.0.0.1, 8.8.8.8, etc.)
- MAC addresses
- Street addresses ("123 Main St")
- GPS coordinates
- Dates (possible DOBs)
- EIN/tax IDs
- Home directory paths not caught by smart patterns
- Shell prompts (user@host)
- Git remotes (reveals username/org)
- Environment variable assignments (HOME=, USER=, etc.)
Shows a floating dark warning banner (top-right, auto-dismisses
after 15s) listing each detected item with its type, value, and
hint. Skips values already in the user's identity config.
Also shows PPI warnings in the popup Test tab and adds toggle
in Options to disable auto-detect.

License: Changed from MIT to BSL 1.1. Free for personal use,
commercial use requires a paid license. Auto-converts to MIT
on March 26, 2030.
Export/Import: Options page now has "Transfer Data" section:
- Export All (plain) — JSON file with all identities, mappings, settings
- Export Encrypted — AES-256-GCM with PBKDF2 password derivation,
saved as .ssbackup file
- Import — handles both plain and encrypted backups, prompts for
password if encrypted
Crypto uses Web Crypto API (browser-native, no dependencies):
100k PBKDF2 iterations, random salt + IV per export.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Storage issue: Chromium/Brave keeps storage.local data even when
an unpacked extension is removed and reloaded. Added "Reset
Everything" button in Options → Danger Zone that clears all data
(double-confirm to prevent accidents).
Reveal mode: Now re-runs revealAllResponses() every 2 seconds
while active to catch streamed content and dynamically loaded
responses. Adds console logging for reveal toggle state changes
to aid debugging. Cleans up interval when reveal mode is turned off.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Interception is now completely inactive until the user configures
at least one identity field or explicit mapping. Before that:
- Icon shows gray (unconfigured)
- No fetch/XHR hooks fire
- First-run banner tells user to set up
Custom domains: clicking "Add Domain" in Options now triggers
the browser's native permission prompt via permissions.request().
No more manual chrome://extensions site access step.
Icon states are now:
- Gray = unconfigured (nothing will happen)
- Black = active and protecting
- Blue = reveal mode on
- Red = manually disabled
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Adds a secret scanning layer that runs after identity/explicit
substitutions. Catches secrets the user didn't configure:
- API keys: OpenAI (sk-), Anthropic (sk-ant-), Google (AIza),
AWS (AKIA), GitHub (ghp_), GitLab (glpat-), Slack (xox),
Stripe (sk_live/test), SendGrid (SG.)
- Auth: Bearer tokens, key=value assignments (password=, secret=,
api_key=, token=), private key blocks (-----BEGIN PRIVATE KEY-----)
- Connection strings: mongodb://, postgres://, mysql:// with creds
- PII: SSN (xxx-xx-xxxx), credit card numbers (Visa/MC/Amex/Discover)
Redacted values shown in red in the Test tab. Secrets are truncated
in the activity log (first 8 chars + "...") to avoid logging the
full secret. Enabled by default, toggle in Options.
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
- Add custom domain support in Options page so users can add
self-hosted AI services (e.g. https://ai.myserver.com)
- Background worker dynamically injects content scripts on
custom domains using scripting.executeScript
- Add optional_host_permissions so Chrome can grant per-domain access
- Rewrite README: add clone step to Firefox instructions, clarify
what "credentials" means in step 3, add Windows commands alongside
Mac/Linux for every terminal step
- Bump version to 0.2.0
https://claude.ai/code/session_01Dvgwe7XMoSxnWXkih8p1Cw
Chrome Manifest V3 extension that intercepts personal data and
substitutes it with user-defined replacements before sending to
Claude.ai. Hooks fetch() in the page's main world to catch API
requests, with bidirectional substitution (real→fake on send,
fake→real on display via reveal mode).
Includes popup UI with mapping management, live test/diff view,
activity log with badge count, options page with import/export,
and Shadow DOM traversal for Claude.ai compatibility.
