Firefox Community Forum

I have issues discerning where each of my desktop windows are. To help with this I use gtk.css styling to add a border on all of my desktop windows. For some reason, Firefox does not draw this border.

Is there any way to apply a border around the Firefox window?

I was able to get a border around the navigation area of the browser by adding a userChrome.css file but I don't see any way to do the same thing for the whole window.

Can this be done in userChrome.css? Using gtk.css styling? Any other setting or file?

I am running Firefox 155.0.1 on Ubuntu Linux 26.04.1 LTS using the Gnome 50 desktop.

Hello everyone.

Firefox updated today. I don't know—maybe some people like the new design of the tabs, the buttons in the drop-down menus, and the gradient borders around the active tab and the tab bar itself. But I’d like to revert to the old interface. How can I do that?

Thanks!

Up until recently (apologies, I do not know which version) when editing userContent.css on Debian 12 in the ' Developer Tools ' I could just use CTRL+S to save my changes and all was well.

Now it appears to have forgotten where it loaded in the first place, because (when using the shortcut or the 'save' link under the name on the left) it just opens the user's home folder at its root level or ' ~/ ' ...

Is this a bug that I should raise at bugzilla? Or has another bug fix messed this functionality up somewhat?

This is the ' mozilla-deb ' / ' Mozilla Firefox Debian Package ' currently at version 154.0 which is usually updated weekly.

this old man cannot find the home button? I thought i had looked everywhere i could imagine but it must be right where i couldn`t imagine, I would certainly appreciate some help. Thank you for your time and effort.

When entering the "customize Firefox" page, the option to enable or disable the title bar is missing. From looking at pass guides it used to be on the bottom left of the page but now it's gone. In case it matters, I am not in fullscreen mode.

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?
