A new update seems to have fixed the issue. Working with no problem now!

It's always been a very good plugin, and now I'm concerned about its recent malfunctions. Every time I launch Firefox, I have to turn this plugin off and back on in order to actually make it work. Please fix?

how can this official firefox plugin be broken???

Good

For those who are having issues on 132 with the theme not loading on startup, go to the about:config page and leave ""extensions.activeThemeID" blank.

Edit: It keeps reverting, changing it to "firefox-color@mozilla.org" has not made it revert yet.

new update fixed it!

This add-om longer works as of newest versions of Firefox. I hope it will soon be updated so that it can work again since I have used this add-on for years without any issues. Since the last update it no longer functions until manually enabled, some parts still don't function after manually enabling. Dependencies and deprecations are likely to blame.

Es funktioniert hervorragend, aber nur, wenn das standard "Hell" oder "Dunkel" Theme in den Einstellungen ausgewählt ist. Das standardmäßig aktivierte Theme, dass sich an den Systemstandard anpasst funktioniert leider nicht mit diesem Add-On.

Used to work great; in Firefox 132 it often doesn't work when the browser starts and backgrounds all revert to white. Worked great in at least Firefox 109 and earlier. It also no longer affects top menu bar menu backgrounds and right-click menu backgrounds. This is one of the reasons I don't normally update the browser... because it breaks extensions and it's a nightmare and takes hours of time to try to troubleshoot, often with no resolution. Very frustrating.

The theme itself is very interesting, yet there seems to be some problem when using with nightly 133.0a1 Once the firefox is closed the next time it opens the colour theme only pop up for a second then disappear. This happened when using 'always inprivate' as well as normal tabs (I have select the add-on to working while inprivate mode) . I wounder if there is a bad setting or some problem when using with nightly.
