[nms808]

Here is the changelog:

Version 136.0.2, first offered to Release channel users on March 18, 2025

Fixed:

    Fixed a bug where "Cookies and site data" and "Temporary cached files and pages" were unexpectedly enabled after updating to Firefox 136 for users with "History" and/or "Site settings" set to clear on shutdown in previous versions.
    Affected users already on Firefox 136 can disable these settings in "Privacy & Security".
    Fixed an issue where the Primary Password prompt appeared in unexpected situations.
    Fixed visibility issues with radio buttons on dark backgrounds. (Bug 1951930)
    Fixed high CPU usage on Windows when the screen was locked or the laptop lid was closed.

Web Platform:

    Disabled support for the CookieStore API due to compatibility concerns. The API will be enabled later once the compatibility issues have been addressed.
