Since updating Firefox from a previous version, the browser no longer displays any Unicode emoji characters. Where an emoji would normally be rendered (👁), the browser instead displays empty space. Websites such as twitter and discord, which use their own artwork for emoji, are unaffected. This has negatively affected my browsing experience.

For illustrative purposes, I will add a series of emoji and include a screenshot of how they are displayed: (😀🙁😡💀). Other characters still display correctly: (β❖♞䷲⎈𐘢𓀺இ). My computer otherwise displays emoji correctly. The issue persists after disabling extensions, and has persisted between computer restarts.

I'm running Linux (NixOS) and Firefox version 148. I've tested on Chrome based browsers and they work fine. Tested on Firefox forks and they also don't display correctly. This is new since less than a week ago.

Thanks for any help with this.

Recently a "gear" icon has appeared on the bottom left of my screen while using Mozilla. It relates to moving the tabs. I don't want to do anything with my tabs. How can I get rid of the icon? The icon reduces the horizontal screen space available. I have a small laptop so this small amount of space is important.

Thanks for your help! Cindy

When using Firefox mobile for android, a black bar appears at the bottom of the screen, above the address bar. Please see attached picture.

It only seems to occur when the "scroll to hide toolbar" setting is disabled. The bar moves upwards when using the keyboard.

Samsung galaxy s25 Android version 15 Firefox version 147.0.3 (Build #2016141759)

Please let me know if any more information is necessary.

When I select Dark Theme, I DON'T wanr to see this. I just noticed this on my Linux Mint desktop machine tonight when I logged in. I also have Dark Reader installed and it isn't affecting ioit eitherit either. Make this go away. It burnsssssss!

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.

Hello, does Firefox has a function where the bookmarks only show in a Bookmarks toolbar when a blank tab is open please? Once a bookmark is selected from the Bookmarks Toolbar, then the Bookmarks Toolbar is no longer needed and should disappear to maximise webpage space.

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 latest update 136.0, a TB icon showed up in the 'system tray'. I'd like to hide it, I have no use for it. Browsing the settings including the advanced preferences yields nothing useful.

on other webpages a black bar drops down from the bookmarks bar and blocks the top of the pages, how do i get rid of it? oddly on this page, the bar does not show up

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

Firefox on Windows 11 has suddenly and without my apparent action started automatically hiding the tab bar and the address bar to give all the vertical space to the current tab. I do not like this (I have big monitors and I want those bars always visible)

How do I turn this one and why did it turn on in the first place?

Thank you for having the Q&A facility.

Hello,

I just set up a computer with Debian 13 'Trixie', and I downloaded and installed the latest Firefox for Linux (version 145) from Mozilla's site.

Then I noticed at first that it wasn't following my GTK theme. Then after testing a bit, I discovered it would respect only themes with names that end in "-dark". I've taken some screenshots and attached them to demonstrate the problem.

firefox-esr from Debian's repositories didn't have this problem. But also, I've got another computer that still has an older distro (Debian 11) installed, and I'm running the latest firefox 145 on that too, and it always respects my GTK theme regardless of whether its name ends in "-dark". So, perhaps this is a GTK/GTK4 problem or something?

Does anyone know about this issue, can anyone help? I would really like Firefox to respect my choice of theme regardless of whether the theme's name ends with "-dark" or not.

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?

146.0 (64-bit) Windows 11 December 11, 2025 Turned on computer this am, Firefox webpage popped up telling me about what is in it's future but now my side bar is black print on really dark background. Help!
