Hello, I somehow have gotten a slimmer sidebar that is attached to my bookmarks sidebar on the left. I can't get it to disappear without losing my bookmarks at the same time. When I re-open bookmarks it has this sidebar again on the side. Is it possible to get just this slim bar to go away? Thank you

During the week of March 7-13, 2026, upgrade(s) caused the size of my bookmarks, fonts and tabs to shrink to barely readable (see attachment) in the Firefox browser window on my Windows 11 PC. I've tried every internet base advice article. How do I increase the size of them?

The Firefox icon looks like it has a shopping cart on the top-left hand side. What is this for? It is only happening on the Windows 11 taskbar (not the desktop or menu shortcut).

A heart has recently been included in the Firefox icon in my taskbar. What's the reason for it and what do I have to do so that the Firefox icon no longer has it? I've run a number of antimalware programs and they came up with nothing.

I'm on Debian 13 stable with firefox nightly (tarball) downloaded from the firefox website with firefox running on wayland. I don't recall the exact time / build that this issue happened, but it has been persistent for over a week or two already.

The issue I am seeing is where secondary menus or popups do not scale properly in firefox. This includes Popups for extensions, right click menus, or even link previews (long click left mouse btn).

Things I tried with no luck:

• Restarting my computer
• Restarting firefox / Updating firefox from the firefox website (https://www.firefox.com/en-US/channel/desktop/)
• Changing my display scale (100%) to (90%)
• Changing firefox display scale from (130%) to (100%)
• Refreshing firefox through the settings (aka clearing extensions and all the other stuff)
• Switching to X11 and back to Wayland... X11 worked fine, but back to Wayland just got things borked again
• Updating all system packages on Debian (nothing much except for security updates on debian stable)

Now the questions I have:

1. Is there a way to fix this issue? 2. Where could I file a bug for this issue? 3. Are there other people with this same issue?

When i downloaded Firefox yesterday i noticed my desktop icons the pictures changed to Firefox picture is there any way i can them back to the way they were before. Barbara Hudson.

Firefox updated to 151.0 last yesterday and now the background of the search selection box has changed color to white from its earlier setting. I have tried a bunch of things but cannot find the CSS needed to restore it to what it was (it was overridden with an image). The image below shows the new, white, version, and what I am trying to do is restore it so that it is overridden with the same background image as the rest of the header. What is the rule needed to override the background of this new box (the box with the colorful "G" and downward caret)?

Hello, after ff updated, gray line appeared. It does not disappear after changing theme. I am using laptop and a monitor. On laptop browser window goes fully to the top, but when i drag ff to the secondary monitor, gray line appears. I will attach photos.

For the last couple of days, the address bar on the web apps that I've installed to my taskbar has been shrunk to about a third its usual length. I don't have flexible space put anywhere on my toolbar, and the problem is only on the sites I've put in the taskbar, not in regular browser windows. Is there a way to fix it, and get it back so it reaches all the way to the extension icons?

I'm using Firefox 147.0.1 on Windows 11, Version 25H2, Build 26200.7623, if that helps

My address bar disappeared. I can get it back by hitting F10 but it doesn't stay. How can I get it back and keep it? When I go to the Customize Toolbar setting, the address bar is not there.

How do I enable syntax highlighting when viewing the mark up of a web page, using the "view-source" functionality of the current tab.

It no longer works for me, I need to use this feature so I can find errors in my HTML markup.

Does the "view-source" feature have any optional settings available to the user and how do I find them using the about: option

TIA.

After update to 141.0.3(64bit), sidebar comes with waste space, as pink area in attached image.

It didn't shows in these years I'm using FF, I want to remove it but keep sidebar exist, like it was before. Where can I adjust it ?

If it's needed to be exist, why not put it on top of Sidebar ?
