  • Version 1.4.2

    Released Oct 20, 2026 - 36.17 KB
    Works with firefox 140.0 and later
    Version 1.4.2

    FIXES
    - Logouts are now verified: the kill switch re-checks, retries leftovers, and clears sites a second way (by hostname).
    - Open tabs on your listed sites are blanked before the keybind closes the browser, so they can't re-create your login.
    - If a cookie can't be removed, you get a notification instead of a silent failure.
    - Subdomain site data (like gist.github.com) is no longer skipped.

    PERFORMANCE
    - Wipes are much faster: the keybind now finishes in about 150 ms instead of about 1.6 s in testing.
    - Steps run in parallel, and the safety pause only happens when a page on your sites is still open.

    NOTE
    - If you stay logged in, make sure the site's login domain is on your list (YouTube logins live on google.com).

  • Version 1.4

    Released Oct 18, 2026 - 34.8 KB
    Works with firefox 140.0 and later
    Version 1.4

    NEW
    - Nuclear option: wipes the browser data you choose, then optionally closes the browser. Double-click the toolbar button or press Alt+Shift+F9 (no window opens; press twice by default).
    - Separate toggles for each data type, plus its own hidden nuclear site list.
    - Change both keybinds in Settings, with a Reset button. Defaults stay Alt+Shift+C and Alt+Shift+F9.
    - Edit your site list inside the extension. It stays hidden until you click "Show my sites".
    - Site access is requested per site, not for all websites.

    IMPROVED
    - Firefox container cookies and subdomain site data are now cleared.
    - If a shortcut can't run, you get a notification and the browser stays open.

    NOTES
    - Firefox doesn't allow symbol keys (= + - ) in extension shortcuts.
    - No data is collected and no network requests are made.
