Details

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:133.0) Gecko/20100101 Firefox/133.0

Steps to reproduce:

I developed custom theme with auto switching to dark mode, as a reference i use "System theme — auto".

https://addons.mozilla.org/en-US/firefox/addon/solarized-light-dark/
This works well until browser restart, after restart theme stop switching.

Actual results:

after restart FF apply theme in "theme" field of plugin manifest. and stop switching to dark mode based time and theme that set up by system.

Expected results:

Theme should change their lightness based on system mode.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Component: Untriaged → Widget: Cocoa
Product: Firefox → Core
Component: Widget: Cocoa → General
Product: Core → WebExtensions

Update: i find out that same happens with official system theme.

Hello,

I could not reproduce the issue on the latest Nightly (135.0a1/20241127212333), Beta (134.0b2/20241127093757) or Release (133.0/20241121140525) on neither macOS 11.3.1 nor Windows 10.

With the linked theme installed, switching the system theme from the OS will correctly switch the theme in Firefox as well, including after a browser restart.

Could you share about:support?
