Firefox Community Forum

Due to muscle menu or not needing to think about it. Split should either be near the bottom of the context menu or you should be able to toggle it in settings. The amount of times I have gone to click a link to open in a new window only to split the view is driving me crazy.

For a while now firefox has been unable to enter fullscreen when pressing F11. Instead all it does is move the "Scroll forwards", "Open a new tab", and "List all tabs" button over slightly (The buttons on the top right, next to the minimize and close buttons).

I don't know what's going on with firefox.

Firefox Version 142.0.1 (64-bit)

When I swipe to the left, Firefox navigates Back & when I swipe to the right, Firefox navigates Forwards. It is VERY ANNOYING!!!! It's really easy to do this accidentally while scrolling around a large web page. When you go back, it deletes all data that was filled out on the web form causing DOUBLE the work. How do I turn it off please? Win 10, FF 142.0.1 64-Bit

not a real question and not waiting for answer.

the "Open all in tabs" menu that appears at the bottom waiting for you to click on it by mistake. we need a way to remove that option while also disabling the middle button over the folder to open all bookmarks over the tabs. It also should be a default because been using firefox since version 1 (previously Netscape Navigator back in 1998) and I rarely had the need for something like that.

Firefox under linux x64 v 148.0.2

Linux madcat8.local 6.12.30 #1 SMP PREEMPT_DYNAMIC Thu May 22 18:38:20 CDT 2025 x86_64 Intel(R) Core(TM) i9-14900K GenuineIntel GNU/Linux

asked chatgpt and it suggested some fixes but apparently userChrome.css is actively being ignored. from the look of things, seems like I will have to stick to an specific version like I had to do with Thunderbird after version 102 where ugly UI changes were implemented.

have fun.

Firefox suddenly has an AI assistant that pops up on a tool bar on the left side of the screen with a green dot beside it. I want to turn this off and make it disappear, if possible. Please tell me how to do that.

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?

I've found out that you can create custom prompts for the AI sidebar with the configuration `browser.ml.chat.prompts.*`. Usually, this is done with the selection text. However, I'd like to pass the URL instead. I could use `%url%`, but that does not include parameters after `?` and hence does not work for Youtube.

Is there any variable that I can use to pass the full URL including parameters of the URL?

I operate with several to many windows open (and many tabs). Firefox (Mac) used to list the open Windows in the Window menu in the order I originally created/opened each window. A while back, FF started sorting – and re-sorting! – the list of open windows alphabetically according to the Tab that is currently active in each Window. This means that the window appears in different places in the Window menu list according to the name of the Tab. I DO NOT LIKE THAT because the it makes the Window hard to find.

Is there any way to set this to operate the way it used to - keeping the Window list in the order first opened, regardless of which Tab is open?

Hi I see that Firefox has the option to ask an AI chatbot, with your options for AI being Claude, GPT, Gemini, and Le Chat Mistral. What I'm not seeing is an option for Lumo, Protons new chatbot. My question is is there any future support coming for Lumo, or better yet, an option to let FF users choose ANY chatbot, not just these 4?

My friend recommended this browser to me. When I tried to customize it, I couldn't find an option to change the hotkeys to my preference. I consider this feature important since I use it for work. Can I do this somehow, and is there any plan to add such a feature to the settings?

I am looking to be able to INDEPENDENTLY close Firefox (Standard) windows separate from those running in a Private session.

ATM, it does not seem possible to close just one type of Firefox session without the other.

I see this possibly as a simple about:config switch which would allow one to close ALL Standard or Private windows with the respective system tray icon's "Close (All) Windows" OR the Menu's Exit selection. No other behaviors need change.

USE CASE: I frequently use both types of windows and will sometimes close Firefox Standard and unintentionally loose tabs I have not saved in Private.

Hi,

I use the Page Info window quite regularly, it used to be accessible via the right-click menu but this seems to have been removed in recent updates. I can still access it via Ctrl+I, but this isn't as convenient as using the menu.

Could you please tell me how I can put this useful feature onto the menu / toolbar as a shortcut?

Thanks

Owen.

I opened Firefox today to find that nothing would show up, at first I tried clicking on the icon on the taskbar, but it just made the icon bounce with the window briefly popping into view. That's when I realized that Firefox was completely offscreen and unusable.

For context, last night, I had 3 windows open, two were regular sessions, the last one was a private session I had open on a temporary second monitor that I unplugged afterward. My dad lended it to me, so I'd rather not ask him again unless I absolutely have to. I closed them in order making sure to close the default window last thinking that Firefox would open there next time I launch it, but comes tomorrow and when I launch Firefox it opens off-screen and I can't interact with the window at all.

There also seems to be no way to bring it back directly to my screen on this garbage OS everyone calls "windows 11" according to their help forum: https://learn.microsoft.com/en-us/answers/questions/4139775/app-runs-off-screen-in-windows-11?page=2#answers

So, I'm commenting here via brave browser, first to report a bug because I don't think Firefox should remember the last position of a private window of all things, but also because I don't know where else to go to ask that question since windows 11 itself cannot seem to have an option to solve this problem either. I know the position is stored in the profile folder, so what should I edit in there to get Firefox back where it should be? No, I will not delete/reset it it has a ton of search engines and settings that Firefox won't sync.

I am trying to disable the text segmentation behavior in latest Firefox(v151), but I have encountered an issue where changing the preference in [about:config] does not seem to have any effect.

Details:

   Target Preference:  intl.icu4x.segmenter.enabled
   Current Setting:       false

   Problem: 
   Even after setting this to false (and restarting the browser), the text segmentation behavior (such as word selection logic) remains unchanged and appears to still be using the ICU4X engine.

   Reference:
   https://support.mozilla.org/en-US/questions/1440483#answer-1638092

I would like to know:

  1.  Has this preference been deprecated or hardcoded to true in recent versions of Firefox?

   2. Is there any other way to disable the ICU4X-based segmenter or revert to the previous segmentation logic?

   3. If this is a known change, is there an alternative preference to adjust how word selection handles specific languages (e.g., Japanese)?

I am using the latest version of Firefox. Any insights or workarounds would be greatly appreciated. Thank you in advance for your help!
