I-Firefox Community Forum

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).

<See screenshots>

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?

I've recently noticed that the minimize button on the top right of the screen is missing, all I have is the close app button and a drop down. I'm on Bazzite, I have the sidebar disabled, I've already done a refresh. The only thing I really haven't done is a full uninstall then reinstall, but I wanted to see if there was a setting I missed anywhere. I've attached a screenshot of the drop down and close app button, but no minimize.

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 am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

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.

So, I recently updated my copy of Mozilla Firefox, and I noticed something strange. The button for the built-in VPN is disproportionately large to other buttons and clickable elements. I don't see it in the release notes, so I doubt this is an intentional design choice by the UX team, at least I hope it isn't. Any help will be greatly appreciated, as it is really distracting.

If it helps, I'm using Mozilla Firefox 151.0.2 running under GNU/Linux Debian 13 Trixie as a Flatpak.

Moments ago I rebooted my computer after a long day of heavy use (it's old). After rebooting and opening my Firebox Browser, I noticed all my Bookmarks were gone. I created a Firefox Bookmarks Export file on another desktop computer using a thumb drive and plugged it into my current desktop computer, and imported the Bookmarks. Great. They all seem to be there again. But the entire appearance of all the websites I regularly use have changed. I use Google Calendar and all the colors are gone. On my other computer, all the different tasks I've created still retain their colors with white lettering, but on this latest version of Ubuntu machine after the reboot, all by tasks are plain white with Black lettering. I compared the settings for Appearance on my two different computers and they are exactly the same. I couldn't Login to X on this machine after doing so numerous times, and after I logged into Bluesky, the appearance was completely different. I don't know what happened. The two attached screen grabs show the difference between this computer and my other one which still shows the color combinations that I want back within Google Calendar. Any idea what went wrong? Also, I tried to click the checkbox below that says, "Email me when someone answers the thread," and I could not. It wouldn't accept the check mark.

So my question is Firefox is on my Cent OS 10 machine and it only shows the close button on the upper right corner, I would like to know two things, 1. How to add the Minimize, Fullscreen buttons to just the close button on the upper right corner. 2. How to get my menu bar back - the home button and all of the other goodies that normally show on the left of the browser just above the Forward, back and refresh buttons?

Thanks in advance for the help.

Same Problem as here but thread is archived: https://support.mozilla.org/en-US/questions/1465988

It has always worked great until now, but it seems that it no longer works with Firefox 147.0.1. Does anyone have any idea how to fix this?

On Linux Mint 22 on my desktop, the buttons in the RH top corner are tiny. I have measured the minimise line and it is under 2mm long.

I have tried various searches to see if these controls could be made larger, but most questions suggest changing the theme. I don't want to do that, and I'm sceptical that it would make any difference anyway.

Has anyone got any suggestions how they could be made bigger?

I'm using the MATE desktop.

Thank you

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.

Hi!

How do I get the sidebar (with vertical tabs) to be expanded whenever I open a new window of firefox? Despite always opening it, whenever I open a new firefox window, it is collapsed.

I'm using version 149.0 (64-bit) from the Fedora repositories.

Thanks!

On Firefox(Archlinux) i can't change website fonts. "firefox-151.0.4.tar.xz" https://download.mozilla.org/?product=firefox-latest-ssl&os=linux... can't either. Even though FF-snap and FF-flatpak can. How can i fix ?

hello. i downloaded firefox from official void linux repo, and have issue with font rendering or smth. in settings option "Allow pages to choose their own fonts, instead of your selections above" is enabled. don't have same issue in any other gtk apps on my system.

Latest update on Ubuntu force reset the sidebar. Reminder for those that do not want, the process to remove it is:

• Go into about:config in the address bar,
• search for sidebar.revamp,
• set it to false.

From this Reddit thread.

Mozilla. Please do not reset the `sidebar.revamp` for those of us that have gone to the trouble of removing it. Thanks.
