Firefox Community Forum

Like seeekerman who initiated the now-closed discussion at: https://support.mozilla.org/en-US/questions/1433369, I have used Firefox since its first release. With one exception - open image in new tab - I never use tabs. I want all the usable vertical space I can get.

For some time, Firefox on Windows (Windows 11, FF 143.0.4) has been showing a tab bar under the menu items, and above the bar with the URL etc.

How can I hide this when the FF window has only one tab, which is almost all the time for me?

The solution provided to seeekerman in that discussion, on 2023-12-08, was to create a userChrome.css file with some special incantations. I tried this it did not work.

Hi there,

For some reason, all my text has been showing up as bold on my Firefox web browser. However, the same sites do not appear as bold on the mobile Firefox app or in a private Firefox web browser.

While I thought it applied to many different fonts, it seems to specifically target Roboto. This is especially troublesome because my photography website has all body text as Roboto:

https://www.koby.photography

This was not always the case, but one day everything began appearing bold several weeks ago. Text that is italicized seems to stay in italics and not bold.

I greatly appreciate your help and support. Thank you in advance

Two questions .......... You have my operating system as windows 10, it is windows 11 ??? ......... 2nd question ......... when I bring up Firefox it shows the weather for Chicago, I live in Minneapolis/St. Paul area, following your weather location change instruction, the weather still goes back to Chicago.

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.

My firefox on my Mac will not open in full screen mode. It use to open in Full screen, but now no matter what I do when I close it out then try to reopen it, it opens in half screen mode. I set it to full screen mode in the setting but no luck. I tried deleting it and re-downloading it. I tried every tip online but nothing works.

Does anyone know how to get rid of that icon in tabs with the newest version? I have found several mentions of code like below, but they are anywhere from 7 months ago to years ago and don't seem to work with the new update:

/* Disable unmuted icon */ .tab-audio-button { display:none !important; }/* Disable unmuted icon */ or .tab-audio-button { display:none !important; }

or something with: .tab-icon-overlay

thanks!

bold text i cannot see the new tabs since they are way too small now. Yesterday they were fine but now they are made for people with normal vision not half blind people like me. Your help button is totally useless and made for people that are programmers. NOT for normal people like me. I just cant see very well and shouldnt need to use a magnifier to read the tabs and seach bar along with my bookmark bar. I can see they web pages fine but I need to see the things above that. It was working fine yesterday but some idiot who doesnt with good vision who is ignorant about people without good vision

Hi, I cannot get the red squiggle line for spell checking. I get a weak yellow highlight. I have tried all the about:support - changing to string, red etc, closing and restarting. It is not working. Please provide solutions. TX

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!

The weather widget on the homepage sponsored by accuweather is missing a lot of major cities that were available before October 2025. They are available in accuweather, but for some reason my widget defaulted to singapore, and I can't manually select cities like chattogram / dhaka or even new york even though the are available in accuweather.

Someone had me do an add-on. I have no idea what the add-on did. Nor do I know how to use the add-on or if it installed correctly. No one gave instruction on how to do what I am asking . So I am stuck with the need to make my scroll bar wider. I need detailed instructions for an idiot on the computer.

Is there away to prevent the auto-unhide of the menu bar in full screen mode when the cursor moves to the top of the screen? I have searched for answers to this and found some old posts about creating a userChrome.css file but I couldn't get it to work.

Here's my use case. I access a remote desktop through Citrix for work. I use a browser via Citrix Lite instead of Citrix Workspace because the desktop will dynamically adjust to the window size when I don't need it in full screen which Citrix Workspace will not do. However, the auto-unhide feature of menu bar when the browser is in full screen mode also causes the desktop to dynamically adjust when it drops down and again when disappears. This forces me pause when trying to work because it happens often since I'm using a a large monitor with multiple applications open with tool bars on the top rows. I know that I can not hide the menu and address bar but don't want to lose the extra screen real-estate. I would much rather have a keyboard shortcut to reveal the menu bar or some other option.

Firefox 143.0.3 on Windows 11 24H2. I normally run my browser window full vertical height of the screen (but not maximized). If my PC goes into screen save due to lack of activity, each time I return and it comes out of screen save, the bottom of the Firefox window has risen vertically by about 15-20 pixels, and there is now a gap between the bottom of the FF window and the bottom of the screen. If I go in/out of screen save again, then the gap increases again as the windows shrinks further. The top of the FF window doesn't move, only the bottom.

This problem doesn't happen with the window size of any other app that I use if I size the window the full height of the screen and go in/out of screen save - eg the Thunderbird window remains the full height of the screen.

Any suggestions on a possible cause and how to fix the problem? It isn't just the latest version of FF that has the problem - it was also there with previous versions.

How do I enable syntax highlighting when viewing the mark up of a web page, using the "view-source" functionality of the current tab.

It no longer works for me, I need to use this feature so I can find errors in my HTML markup.

Does the "view-source" feature have any optional settings available to the user and how do I find them using the about: option

TIA.
