I want to add a dedicated search bar next to the address bar. When I search how to do this, I read: To add a separate search bar in the Firefox browser, navigate to Settings > Search and then click on "Add search bar in toolbar". This will place a dedicated search bar next to the address bar. But when I search for "Add search bar in toolbar", I get a message there are no results in Settings. I have Windows 10 laptop.

I have attached an image of the setting panel that used to have options for the home screen of Firefox. There are no wallpapers to choose from and the Home screen is barren.

Not sure if this is related, but I had just enrolled to continued Windows 10 updates and then found that CCleaner wouldn't run anymore. I couldn't get it fixed no matter what I tried so I had to reinstall an older version of it. It opened up Chrome browser on my computer after finishing the installation, and now, I can't figure out how to make Firefox the default browser again. Windows 10 Home Alienware 15R4.

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

Version: Firefox 129 Ubuntu/Debian I'm using the Proton theme in Firefox and would like to revert the tabs to their previous, non-floating style. I've tried using the [profile]/chrome/userChrome.css method and enabling toolkit.legacyUserProfileCustomizations.stylesheets, but this hasn't worked. Is there another way to achieve this? Thanks for your help in advance!

This recently happened on Firefox for my laptop and the characters are broken. I've tried re-installing and removing the files Application Support/Firefox, but the issue still persists. The language is set to English CA. Can anyone help with this please?

It seems that my Bookmarks are opening SOMETIMES back onto itself. How do I adjust my settings so they don't seem like they overlap back onto each other? Wasn't sure if this was a Firefox setting I overlooked or a Windows 10 problem. Hopefully the attachment clarifies it more.

[article] This article claims there is an "AI Controls" section in Settings. This is not found in v 147.03 (up to date) for Mac. Please let me know how to disable all AI in Firefox.

I have two computers. Both sign into the same Firefox account. Both instances of Firefox are the same version (134.0.1 64-bit).

On my main computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the first image (firefox_2025-01-19_17-42-57.png)

On the other computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the second image (firefox_2025-01-19_17-43-57.png)

How to I get both instances of Firefox to do the same thing when creating a new tab, i.e. organize the recommendations like the second image?

For years, I've been looking for a way to disable the space bar from acting as a page down button, including trying out scripts to solve it, but please let users disable that shortcut in the about:config page.

It is difficult for me, since I see that ability to change what the backspace does is available, but there's no option for the space bar. The space bar is something that I often accidentally hit, and it would be of immense relief to me to no longer have that issue of it paging down what I reading. This is my request, and there are others who also feel similarly.
