Hello

After update to FF 150.0 I have an issue I can't solve myself. My old theme that I was using for many, many years changed colours, because now frame colour corresponds to whatever FF uses dark theme or light theme for some panels like bookmarks, bookmarks editor e.t.c ( I assume it). So if frame is dark all other elements switch to dark mode. I`m looking for a way to change it back to how it was before FF 150.0, meaning if frame is dark I want all rest element of FF to become light themed. For instance: in manifest.json if "frame": "rgb(31, 34, 60)", everything else turn dark if "frame": "rgb(131, 134, 160)", everything else turns light Default themes won't work for me ( v.bad eyesight ) Is there any entry I can add to manifest.json to get what I want? I mean: if "frame": "rgb(31, 34, 60)", I need everything to use LIGHT themed colours.

An Add-on (a theme) I've been using, Graphite Grace by compilan, has been removed with the following message:

"This add-on is blocked for violating Mozzila's policies and has been disabled".

As a user, I feel I have the right to know what policies were violated, and whether the add-on was indeed malicious as well as what data may have been compromised. Where can I get that information?

Hi! I updated my browser and ever since then I can't re-enable any of my themes. Even when they say "Enabled", nothing happens. The only ones that work are the light and dark theme as well as another one of the Firefox themes. I tried going on the users' pages and downloading them again, and also tried downloading new ones. Neither of these things worked. I am basically just asking how to re-enable my themes and extensions so that I can customize my browser. Thank you! :)

Добрый день(или другое время суток)! Я столкнулся с такой проблемой, когда захотел изменить темы на телефонной версии firefox на более красивые, заметил что данная функция ещё не сделана. Планируется ли создание такой персонализации как на ПК? Если вы не планируете заниматься этим обновлением то пожалуйста напишите, чтобы я его не ждал. Благодарю за понимание!

It used to be when I would choose a theme that when a new tab or window opened that the theme was there. It hasn't been doing even with themes that I have used previously.

What is causing this?

Looking forward to your response. Thank you in advance, May Hughart

Hello! Have a quick question concerning Firefox Themes. I have a rather large monitor (5120x1440). When I download a theme, the left quarter of the theme is a solid color (not theme related), see attached screenshot. Is this because the theme was made for small resolution? Can I increase the resolution on the downloaded theme? Thanks! Grateful Firefox user - Jeff

I have three laptops which are synced. One function I do not want to sync is my individual selection of themes. Every time I change the theme on one, the other two go blank. In my sync settings I sync Settings and Add-ons. Do I need to disable one of these to correct the ongoing problem?

I have a custom theme enabled on my browser. Every time I log into Firefox on a shared university computer my theme is turned off for that desktop aswell as my personal laptop. I have to manually enable it on my personal devises again each time after using school computers. Is there a way to prevent this?

I have installed an animated theme for my home page a while back, but recently if I minimize firefox the memory usage increases until it freezes my pc completely. I know this issue has been reported as Bug 1828587 2 years ago and it is said that it is fixed, but here I am experiencing the same thing. I would appreciate any help since I am not that good at coding a css file. Here is my userContent.css code if maybe i set something up wrong:

@-moz-document url("about:newtab"), url("about:home"), url(about:privatebrowsing) {

   /* Sets background image and autoscale image to browser window. */
   body {
       background-image: url("wallpapers/wallpaper.avif") !important;
       background-size: cover !important;
       background-repeat: no-repeat !important;
       background-attachment: fixed !important;
       background-position-x: center !important;
       background-position-y: bottom !important;
   }

   @-moz-document url("about:newtab"), url("about:home") {
       .top-site-outer .title {
           color: white !important;
       }

       .logo-and-wordmark .wordmark {
           fill: white !important;
           color: #00aaff !important; /* fallback for text */
       }

       .context-menu-button.icon {
           fill: white !important; /* for SVG-based icons */
           color: white !important; /* for any text-based fallback */
           opacity: 1 !important; /* ensure visible even when normally dimmed */
       }
   }

The second part is to make some of the text on my homepage white so it is visible.

As above themes not working on latest version of firefox difficulty reading menu & tabs bar as light blue needs to be dark coloured

Also have difficulty reading your website because of white background will not work on dark mode retinopathy burn

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

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)

Hello!

SECERITY: LOW, COSMETIC DESCR.: I love how many yhere are beautiful themes for ff. I Like to install any the I think is beautiful and keep enjoing all of them by switching them to see it on FF itself. Now - not aftyer every change of active theme, but after a few/scrooling the order of the Themes on list is re-sorted. It is a little trouble for me as I like to chnge/watch them afew times a day (like person who like to watch theirs clothes, how their look in that clothes, so they keep changing them and see how they look in the mirror). So Id like the list of themes to be fixed, so I can go throuh the whole list and make sure I didn't missed any of my installed themes. OK, I hope I manage to explain it. I'm 40+ yo soft dev. so you can ask me technicall questions. And also: a setting among about:config to change this list behavior whould be absolutely enough solution for me.

Best regards, Michał Dąbrowski

As per my title, where can I find a themes toolbar background image and change it? I have tried looking for manifest.json and header.png files for the theme but I can't find it.

Or is there a way I can override it using CSS somewhere?

Windows 11

Cheers

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.
