Firefox Community Forum

Used to be able to set default background color when not specified by site After last update this feature appears to be gone I found another setting that seems to override site background color and colors. Very ugly, had a hard time deciding reading site information. How do I get what I had back?

I've looked at this page:

https://support.mozilla.org/en-US/kb/customize-firefox-controls-buttons-and-toolbars

It shows the toolbar customization page like in the attached image I've named Customize Toolbar.

In my Firefox (138.0.1 64-bit on Windows 11), it looks like what I'm showing in the attached image I've named My Customize Toolbar.

I like the background shown in the Mozilla documentation. I hate the background I've got. I didn't choose that color. I have no idea where it's coming from. I sure would like to change that disgusting color to white.

How do I do that?

I love the pinned tabs feature. However, when I pin tabs, any more than 5 won't show up on the contracted sidebar. In the example I've uploaded, t here are 8 pinned tabs, viewable in the expanded sidebar as icons four in a row across the top. The second image shows the same window contracted, with only five of the 8 pinned tabs visible. The others are still there, but I can't see/access them without re-opening the sidebar. How do I get Firefox to show all the pinned tabs in the contracted view?

Thanks!

How do I get rid of the sidebar and show only bookmarks on the left? The combine operations, as of now, is taking up a quarter of the screen. I do not need the sidebar just the bookmarks.

In regards to the Privacy & Security under Tools. How can I change the size of the fonts?

In viewing Privacy & Security, I was in Passwords verifying info and I had been working on a spreadsheet through Open Office I changed my fonts size on the spreadsheet but it seemed as though it changed it in the settings for my passwords under Privacy & Security. How can I resize my fonts on the Mozilla Firefix application?

I updated Firefox and now the UI is in a font so tiny as to be illegible, even though it is set to be quite large -- all the way to maximum as I tried to resolve this issue.

Nothing I do makes Firefox usable since the update. (Edge was not affected, of course. This is a Mozilla problem.)

Has anyone else experienced this, and if so, did you find a way to restore the app so that it can be used?

Yesterday, something in my Firefox 138.0 (64-bit) settings changed spontaneously. Streaming and some other site backgrounds changed from black to transparent. Headlines on all sites turned to green. When viewed on Edge, none of these changes had occurred. I use Automatic, not Dark, mode. Can anybody help me reverse these changes?

Previously I could change the color of ONLY visited links. 138 broke that ability and replaced it with a contrast setting that changes every kind of link color and the page background color/design too. This totally stinks and makes the visited web pages look terrible and hard to read too.

Is there a way to set FF so that ONLY visited link colors can be changed to the preferred one?

Hello. After updating to Firefox 138.0 (20250421163656), an issue has appeared that causes incorrect transparency behavior in the taskbar. The problem is that Firefox expands to full screen but continues to operate in windowed mode. After enabling full-screen mode (F11), the issue disappears until the next interaction with the browser. Nothing critical, just a bit annoying.

Basically title.

Every time I close the browser and re-open it, the favicons disappear. I use the favicons to navigate to websites on my bookmark toolbar, but they're missing from my regular bookmarks, too.

I found an old thread that appeared similar, and the solution was to take a working copy of the favicons.db file and re-import it if it breaks (while the browser application is closed). However, this did not work.

Any help would be greatly appreciated.
