136.0.1 Firefox Release

March 11, 2025

Version 136.0.1, first offered to Release channel users on March 11, 2025

Fixed

  • Fixed an issue where a cookie size limit caused problems with website cookie management when using the CookieStore API. This could cause login and other state-related issues. (Bug 1950565)

  • Fixed an issue where Control/Command+L did not focus the address bar in new windows. (Bug 1947723)

Unresolved

  • Users clearing "History" and/or "Site settings" on shutdown on previous versions will also have clearing "Cookies and site data" and "Temporary cached files and pages" enabled after updating to Fx136 even if they previously haven't checked these settings.
    Affected users can go to "Privacy & Security" settings directly after the upgrade and uncheck both boxes to avoid getting logged out. (Bug 1952564)
