Firefox Community Forum

Firefox popped up an offer to change the screen to dark, which I did. I don't like it, want to change it back. I went to settings but was unable to make the change.

After an update for Firefox Developer Edition on Arch Linux (I don't know which), my URL bar doesn't show the selected text when typing or pressing Ctrl+A.

In the uploaded image, you can see i typed "e", but it doesn't highlight the entire en.wikipedia.org url. the second result still shows the e's in the URL bolded though.

I've tried disabling hardware acceleration, changing my GTK theme, and also changed my Firefox Theme, yet none work.

Hi.

I'm using Firefox 153.0 on Fedora 44 with GNOME 50. Everything is up to date at this date. I know that Firefox is supposed to support fractional scaling on Wayland since version 146.0. However, it does not work on my device.

As you can see, the first screenshot is when Firefox is in fullscreen mode. Fractional scaling seems to work and the text and picture are very sharp. However, when I resize the window, it looks like Firefox does not support fractional scaling (see my second attached screenshot). The text is blurry and not as sharp as when the window is in fullscreen mode.

I’ve been taking a look at the latest updates regarding the new Firefox design rolling out in Nightly, and while I appreciate the ongoing work and the return of features like Compact Mode, I wanted to share some thoughts from a user perspective, particularly regarding the aesthetic changes.

Personally, I’m not a big fan of heavily rounded edges across tabs and UI elements. For my workflow and visual preference, I much prefer a cleaner, sharper, and more traditional layout.

With these UI evolutions coming down the pipeline, it would be fantastic if Mozilla could provide a built-in option or setting to keep the current/classic style intact while still receiving all the important under-the-hood updates, security patches, and features. Giving users the flexibility to choose between the new design language and a more traditional layout would ensure everyone can tailor Firefox to their exact liking.

Would love to hear how others feel about the new look and whether a classic style toggle would be a welcome addition for you too!

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.

I have already turned off the 3 or 4 different types of firefox suggestions in the settings. Did they add yet another one? I can't find anything about it in the settings. How can I be sure I never get a pop-up suggesting any sort of wallpaper again?

I have just moved from an old laptop to a newer one - a Lenovo Thinkpad. I have installed Linux Mint and successfully transferred my files and Thunderbird. I also synchronized Firefox and all my add-ons, bookmarks and history came across perfectly. While setting up the toolbar from the customise screen I dragged the home page button onto the toolbar and it just disappeared. The home page is set up in settings. It appears the first time I open a window. I would like to be able to go back to my home page at will, how can I re-instate the home page button?

On Arch Linux with the latest version of Firefox, the interface elements turn black due to a theme loading failure. 'This issue persists even when using the default theme.

Going to Settings and disabling the theme (which automatically falls back to another theme) resolves the problem.Re‑enabling the problematic theme does not reproduce it immediately. However, the issue reappears after restarting Firefox.

Fonts are not scaled correctly. Too big and overlapping and too small on same page. Not scaling to fit page. Worse on Youtube and gmail. Screen shot is from this page!

I have my ... what do you call it? ... GTK? set up to widen the scroll bar when I hover over it. Problem is that it widens *before* the mouse cursor has moved onto the narrow bar -- it widens as soon as the cursor moves onto the territory that *will be* on the wider bar and thus, if there's a click button at the very edge of the page, it gets hidden by the expanded bar. Would it not make more sense to only expand the bar if the cursor actually moves onto it?

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 ?

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?

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.

A while ago I made some changes in about:config and also in my ~/.config/gtk-3.0/gtk,css file so as to control my scrollbar and slider -- making them more visible:

/* Log out, and back in for these changed to take effect: */

scrollbar { background-color: #cccccc; } scrollbar slider { min-width: 20px; }

/* dark green: pointer is not in the active window */ scrollbar slider:backdrop { background-color: #00aa00; }

/* green: pointer is in the active window but not on a slider */ scrollbar slider { background-color: #00ff00; }

/* dark red: pointer is hovering over slider but mouse button not pressed */ scrollbar slider:hover { background-color: #aa0000; }

/* red: slider is active */ scrollbar slider:hover:active { background-color: #ff0000; }

/* No effect: */ /* scrollbar-color: blue white; */

... it works half the time. Some pages obey the above settings but other pages continued to show a scrollbar about a mm wide with the slider so faint as to barely be visible. So, in 'about:config' :

widget.non-native-theme.scrollbar.size.override 30

... at least made the narrow scrollbar a bit wider. But how to change it's color? Doing this in a file:

~/.mozilla/firefox/5dqk4533.default/chrome/userContent.css:

html,body{

   scrollbar-color: yellow blue !important;
  }
.... doesn't change anything.  Is there some complete guide to controlling the srollbars?  Nice if it could all be handled in one place of course.

as is the text I read takes only 1/3 of the available width of the screen. In reading mode I can widen that, but many pages lose a lot in reading mode. How can I widen the text in normal mode?
