Firefox Community Forum

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?

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?

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

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).

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.

Running version 146.0.1 No new extensions. Recently, when I hit ctrl+b to bring up the bookmarks sidebar, it opens but doesn't display the bookmark correctly. (image #1) The sidebar opens, but everything is whited out. The same thing happens when I try to open the history sidebar, except that the urls kind of show up. (image #2). Also, when I'm on my homepage, there's a white line on the left side that I can't get rid off. (image #3) I also tried refreshing firefox, but that didn't do anything. Does anyone have an idea what may be causing this? Thanks

Since the last update, my bookmarks sidebar does not open automatically when I open Firefox. A minor annoyance, perhaps, but an annoyance nonetheless, especially since it used to work until Firefox monkeyed around with it unnecessarily.

Every help I've found gives the same answer: Make sure the Bookmarks Toolbar is checked "Always Show." Well, it is checked, it was never unchecked, except that I tried unchecking and rechecking it in the vain hope that it would jumpstart something.

Is there any way to fix this? Or is it cursed forever?

Does anyone know how to remove the the keyboard shortcuts from Context Menus? For example: Ctrl+Shift+O beside Manage Bookmarks, or Ctrl+Shift+H by Show All History? I like having them gone so the menus can be narrower. This code worked until the latest update to FF 143: .menu-accel-container{display:none!important} thanks!

I was experiencing that one bug that locks the sidebar from opening on hover (even with the option enabled) and I was somehow able to change the size of the sidebar while trying to get it to start working again (IDK why I didn't just close and reopen my browser because I know that fixes that) and now my open on hover sidebar is the biggest it can go and it is genuinely unusable. I can't change the size of it while it's on the open on hover option, but changing it back to the fixed/static sidebar and then editing the size does not carry over when I re-enable the open on hover option. Objectively, this is really dumb and kind of hilarious. I know I am dumb for this.

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

Hello Since few weeks (maybe on firefox 132 already, but surely on firefox 133) I observe issue with my firefox UI. While grabbing and holding tab (to change its position, move it on bar), whole tab bar gets thinner which realigns my whole UI. Issue is probably caused by my custom userchrome.css but I need it in current or similar form. Maybe there is some css specialist who can help me remove unnecessary parts of code?

My css is as follows:

.tab-background{ border-radius: 0px 0px !important; margin-bottom: 0px !important; } .tabbrowser-tab:not([selected=true]):not([multiselected=true]) .tab-background{ background-color: color-mix(in srgb, currentColor 4%, transparent); } menupopup > menu, menupopup > menuitem{ padding-block: 3px !important; min-height: 0px !important; }

root{

--arrowpanel-menuitem-padding: 2px !important; }
