SesWi is a Chrome extension (Manifest V3) for saving and restoring login sessions per domain. It captures cookies along with localStorage and sessionStorage snapshots, lets you list and group sessions across domains, backup/restore sessions (plain JSON or password-encrypted OWI), and clean current tab data when needed.
- Data preview — See cookies, localStorage, sessionStorage, and history items before clearing
- Expandable sections — Click to expand each data type and view details
- Cookie expiration status — Visual indicators showing if cookies are Session, Valid, Warning, or Expired
- History preview — View page titles, URLs, and relative visit times
- History count detection — Shows actual number of history entries for current domain
- Fixed CSP violations — Removed all inline event handlers for better security compliance
- Fixed history clearing — Now uses
chrome.history.deleteUrlAPI properly - Fixed cookie domain matching — Exact domain matching prevents accidental cross-domain deletion
- Improved cache clearing — Added fallback for browsers that don't support origin-based cache clearing
- Removed all TODO/FIXME comments (implementations complete)
- Cleaner codebase with proper JS event handlers
- 43% fewer files — Consolidated from 21 files to 12 files
- Modular structure — Clean separation:
core/for Chrome APIs,ui/for interface - Single CSS file — All styles consolidated into
main.csswith Tailwind utilities - Vite build system — Modern bundler for faster development and optimized builds
- Selective storage save — Choose to include/exclude localStorage and sessionStorage when saving
- Clear after save — Option to clear tab data immediately after saving a session
- Enhanced Clean Tab modal — Selectively clear cookies, localStorage, sessionStorage, history, or cache
- Improved favicon caching — Faster icon loading with persistent cache
- Better sensitive domain detection — Expanded warnings for Google/Microsoft ecosystems
- Faster popup load — Reduced file count and optimized imports
- Better error handling — Consistent Response pattern across all modules
- Improved pagination — Smoother navigation in session lists
- Enhanced UI feedback — Better visual states for actions and selections
- Migrated to ES modules throughout
- Removed redundant abstraction layers
- Unified utility functions in
utils.js - Backward compatible — existing sessions will work without migration
- Save sessions per domain: cookies +
localStorage+sessionStorage - Restore cookies only when on the same domain (prevents cross-domain conflicts)
- Three tabs:
Current(active domain),Groups(all domains),Manage(backup/restore, bulk actions, clean data) - Backup/Restore: export all sessions to JSON (plain) or OWI (AES-CCM 256-bit via SJCL), restore with password verification for OWI
- Clean Current Tab: selectively remove cookies, localStorage, sessionStorage, history, and cache for the active domain
- Cached favicons per domain for a faster, informative UI

- Click the extension icon to open the popup
- Header displays the current domain and
Add Sessionbutton - Current tab: shows sessions for the active domain; click a card to open Session Actions (Restore, Edit, Replace, Delete, Backup JSON/OWI)
- Groups tab: grouped sessions across all domains with expand/collapse and pagination
- Manage tab:
Backup All Sessions: export to JSON (unencrypted) or OWI (encrypted)Restore Sessions: import from.jsonor.owifile with password verificationGroup Manage: select domains for bulk backup or deleteClean Current Tab: selectively clear cookies, localStorage, sessionStorage, history, and cache
Note: Session restore is restricted to the same domain as the current tab to prevent cross-domain cookie conflicts.
Declared in manifest.json:
| Permission | Purpose |
|---|---|
tabs |
Read active tab, reload after restore/clean, fetch favicons |
cookies |
Read, delete, and set cookies per domain |
storage |
Store sessions and icon cache in chrome.storage.local |
scripting |
Execute scripts to read/write localStorage and sessionStorage |
history |
Search and delete browsing history for current domain |
browsingData |
Clear cache (optional) |
favicon |
Access favicon API for domain icons |
host_permissions: <all_urls> |
Enable cookie operations across all domains |
- Sessions are stored locally in
chrome.storage.local(unencrypted). Protect your device. - OWI encrypted backups use SJCL with AES-CCM 256-bit. Passwords are never stored.
- Sensitive domains (Google, Microsoft ecosystems) use complex auth flows; saving/restoring may not always work. The UI displays a warning for these domains.
