When I updated to Firefox 146 yesterday, the theme I was using disappeared and I ended up making a new theme using Firefox Color. I submitted it to the add-ons list and it has now been accepted, so now I am using it installed from the add-ons. Ever since I started using the new theme, even before installing it from the add-ons menu, my private browsing window is also using that theme. I want private browsing to use the default dark theme. That way I can easily tell if I'm using the private window or the regular Firefox window. However, I can't find a way to change a setting to go back to the dark window for private browsing. I've already checked about:config and browser.theme.dark-private-windows is set to true. I even toggled it to false and then back to true but there is no change. I looked at the settings for the extension Firefox Color, and it is turned off for private windows. I looked at the settings under the theme add-ons, but I don't see a setting there to turn it on or off for private windows. Am I missing something?

I am now on the very latest version, 146.0.1, and my private browsing window is still using the same theme as my regular window.

Hello

when i scroll to fast, it does this. That would be a minor issue, however, it shifts where the cursor is active, which is mildly annoying. Also, I am using some kind of theme, i believe its Aurora from Firefox.

Thank you for fixing the issue.

Best Regards

I encountered an issue when exporting a theme from Firefox Color. When I downloaded the XPI file, it contained only a `manifest.json` and **did not include the background image files** referenced in the manifest. This caused Firefox to reject the theme as “corrupt” when trying to install or import it.

What I discovered during debugging:

1. Firefox Color provides both a **ZIP** and an **XPI** download.

  The ZIP contains the correct folder structure and the background image files.
  The XPI is missing these files entirely.

2. Because the XPI is missing required assets, Firefox treats the file as corrupt.

3. Importing the broken XPI through the Add-ons Manager or uploading it to AMO also triggers corruption or validation errors.

4. I had to manually inspect the ZIP, extract the proper `images/` directory, and rebuild the XPI myself.

5. I ended up using ChatGPT to troubleshoot the issue, confirm expected manifest structure, correct extension ID mismatches, and verify JSON formatting.

The issue appears to be that Firefox Color’s **XPI exporter is broken or incomplete**, producing theme packages that cannot be installed or validated without manual repair.

It would be helpful if Firefox Color’s XPI export included all necessary files consistently and matched the structure found in the ZIP download.

i am unable to see my installed themes and therefore can not use them. the only thing that i can see is "extensions" and "plugins". i looked online for a few hours and have found no solutions that work.

Good Day,

I am leaving Brave as my default browser for Firefox.... Brave is good, just would prefer Firefox. I used to love it.

The problem is...I have a theme on Brave and Chrome that I love dearly. Is there a way to bring that theme to Firefox? I tried using Firefox Color, but it looked awful.

PS: I am the tech Village Idiot so please talk to me in that vein ;)

Thank you and Warmest Regards, Alisa (Stormwolfe)

I can not get rid of the pink background in the address bar, search box or background space of yahoo mail. I can not find the revert to default theme as previous post from several years ago suggested as a solution.

I set a theme with https://addons.mozilla.org/en-US/fire.../firefox-color/(Firefox Color), I tried changing the theme in settings to light or dark but neither work. I'm wondering if there are other ways to do so in Firefox that I could try. I'm on zen browser which is why it may not have worked.

Turns out you cant use your own stuff until it is approved, Sorry for this question I am absolutely new to firefox workshop. Case closed (Please delete it because I couldn't find how to do that)

I recently updated to Firefox 135.0 on MacBook Pro, Catalina, OS 10.15.7 In the past, with multiple Firefox windows open & multiple tabs open in each, when restarting, "reopen pages on startup" selected, system loaded & ready to go, I'd find all windows, tabs & history available upon launching Firefox. Since update to 135.0, shut down & restart, launch Firefox and I find a single blank new window, no multiple windows, no tabs, no history. I've tried to find [Settings] to make everything come back - no joy, to no avail. Suggestions? Help? Thanks, JS

you are repeating old mistakes. You have become worse than Microsoft. Firefox is not remembering open tabs again. I have supported your Firefox until now but enough is enough.

I have literally over 200 tabs open at a time and recover them every time I reboot Firefox, but they are very disorganized. Is there a good way to organize them, for example, group related tabs together?
