I am searching through the Find more Themes page. They either don't open or I get a An unexpected error occurred when trying to open them. I've updated to the current version, and still not working.

Also I have Grammarly for Firefox added, for my word spell checker, but it keeps using the windows checker. How do I fix that.

I have a problem with contrast-free Firefox. I cannot see what tab is active what is passive. I tried to get better contrast by changing the theme with those available for Firefox. I have tried at least a dozen of them, but all get the sane destiny. It might take a couple of days or a couple of weeks, it comes. I mean after a short period my applied theme disappears and I get the same standard theme.

I have been using the them, Jesus is Lord for years. Suddenly when I open up the attach file box...it has changed colors and it is back on white. I can't do black background with white text. I tried changing it in several places with not avail. Can someone please explain why it suddenly changed colors on me and how to get the original white background with black type? Thanks, Carol

I'm an old lady, not tech-enabled in any way. Please help and thanks.

Hi - I love the themes available in Firefox. However, some themes I use change my Bookmarks section to "dark". I assume that is by design. However, is there any setting in themes that will enable the Bookmarks section to stay on a light setting? If not, may I please submit this as feedback for a future suggestion? Also, the themes affect the look of part of the new sidebar. I would also like to submit as feedback this issue. Thanks in advance for any help!

Your themes aren't working right and for some reason the bookmarks sidebar has gone dark, and MY theme which I created is no longer available. The toolbar up top loses the icons for back space, forward, home, and refresh and I constantly have to re enable the theme to make them reappear. This is getting tiresome and needs fixing.

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?

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
