Until recently (like last week-ish) My Bookmarks Sidebar ONLY showed bookmarks. NOW, within the past few days the "bookmarks tools column" has been added to the screen-view. I have removed the 'tools' but the 'blank column' remains and takes up noticeable space on my laptop screen. How can I remove that 'column' ? Was this caused by a recent firefox update OR a win-365 'auto-update' ? Attached pic of screen - Here at the LEFT side is the 'blank column' with the 'settings Gear' at the bottom of the column. That is the column I want to 'Remove'.

I'm using Ubuntu 24 with the XFCE desktop. I'm installing the debs straight off packages.mozilla.org (currently 143.0.3).

Firefox's title bar, and window manager buttons do not have the same look and feel as the rest of my windows. And I have no idea where they're coming from.

They do change appearance in response to picking the different styles in Settings > Appearance, but the changes appear to be limited to colors only. The minimize, maximize and close buttons look differently than on all other windows, and they are more spread out than in, and the shade button is nowhere to be found.

I'm attaching two small images, the first one is the standard set of widgets all other windows have, and the second one is Firefox's odd duck. I could not find anything in settings. "Extensions And Themes" shows that "System theme" is enabled. Well, it's coming up a bit short...

Hello.

My Firefox browser is missing the close button from the top bar. Minimize and Maximize buttons are present.

This is happening on Fedora 42 With Gnome.

I believe I don´t have any custom theme or user css or extension that could cause this.

Also because, it seems to be hapenning not only in Firefox itself, but also in Firefox based browsers, like Tor Browser.

Anyone has any idea what is hapenning?

Thank you.

Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

• I have verified that the browser itself is technically updated (via Help > About Firefox).
• The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
• This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

Hi, is there a way to customize sidebar to move the controls to the top or bottom of the sidebar? With sidebar open there is a lot of wasted space with just 3 icons - settings, history and sideberry buttons. Not really an optimal situation.

Attached screenshot and another picture explaining where I would like to move the buttons. Either top or bottom of the sidebar is preferable than taking the side.

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

My toolbar is visible when I click on the 'Open a new tab' plus sign at the top. But if I go to a site, either from a search or from bookmarks, the toolbar disappears.

I just (yesterday) had to delete profile, delete bookmarks, delete Firefox, install Firefox, in order to get it where it would save bookmarks again. The toolbar, prior to that, did NOT disappear when I went to a new site.

Please help.

Why can't anyone fix this issue? Every day I have to go to about:config, enter "mica" then change from false to true or true to false to get these buttons to show up. It's ridiculous. I am currently using Firefox version 146.1 on Windows 11. Also, please note if I change the windows widget to true these buttons show up and are usable. The next days I have to change the windows widget to false and they show up and are usable so they work whether or not the widget is set to true or false. The problem is having to change the setting DAILY. I should not be having to do this.

Reference: Firefox Desktop 139.0.1. See the attached image. What does the overlaid blue (cable with plug?) icon mean on top of my Grid Overlay bookmarklet? The overlay appeared after the update to v139.0.1 (desktop) on Arch Linux. And only on top of my bookmarklet. In case it's relevant. The bookmarklet consists of JS that injects some HTML in the rendered webpage and then beckons my grid overlay. Self developed to overlay my own web layouts.

I recently needed to reinstall Firefox to attempt to deal with an issue. It turned out Firefox was not the cause but when the new browser opened, it did not have the Home icon on the toolbar.

I went to "Customize toolbar" and added it but now it shows up on the far right end of the toolbar. It used to be to the left of the URL area. I tried to grab it with the mouse and drag it but it won't move.

Every time I need to jump to a home page I end up going where it used to be. I realize this is small potatoes but is there any way to get it back where it used to be?

I have 2 computers, both with Linux Ubuntu. All of a sudden one of them is missing the File toolbar. It was there this AM but gone now. I looked through the menu and couldn't find where it is that you add the toolbar. On this computer, which has that toolbar, you go to 'view" and there is an item for toolbar. But on the other there are none of those menus and I can't find where to add that toolbar.

I want my bookmarks toolbar to be across the top of the page but I can only find it from the 3 bars at the top right of the screen. When I click on it, I am given the option to hide the toolbar, but it's already hidden. I have also navigated from the View menu as well, and the toolbar is set on Always Show. I have run out of things to try. I am on a laptop with Microsoft Windows. Can someone offer assistance?

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!

After the last Firefox update (146.0), my bookmarks bar only shows thumbnail images. The descriptive text which was previously black text on white back ground now appears to be white text on white background. (Whether my system is set to light theme or dark theme.) This happens on all of my Windows computers (both 10 and 11). How do I resolve this problem?

I just updated Firefox and the bookmarks on the left become all black. Black font on black background. Unreadable. Before that, the font was white.

How do I change that ?

Thanks !

Firefox mozilla recently updated, now the bookmark side bar has made the fonts dark on a dark background, now unreadable. How do I change the fonts back to white on a dark background?
