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.

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.

When uploading files with Firefox, I click the upload button, and the file browser window appears to upload files.

For as long as I can remember, it always defaulted to the last folder location that I uploaded a file, but just a few days ago, it stopped working, and always defaults to my home folder.

How can I make the upload window pop up, default to the last uploaded location? My OS is Linux Mint Cinnamon.

Hi. Now that the 'Open Link in Split View' has annoyingly replaced the spot previously held by 'Open Link in New Window' i keep clicking on it accidentally (muscle memory).

I don't want to have to retrain my muscle memory, but despite creating css file generated by Claude that should in theory remove the option, and putting it the Profile Folder, it will not go away.

How do i remove it?

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

Dear Folks at Firefox, Mozilla

In last few days I really have a big problem with trying to browse with my favorite browser Firefox. It is that cursor always goes to address bar instead of search bar when I am trying to surf the web. I tried all the fixes that I found online with changing things in about:config still with no solution.

I am running on Windos 11 and using latest Firefox version.

Kind regards Aljosha Mileta

I'll be honest, I have strong ethical objections to "generative artificial intelligence" (genAI) on a range of issues, and I have seen no sign that the industry is capable of, let alone plans to address any of them. But I'm not here to debate genAI, I'm here because I require a work enviroment and tools that make it as easy as possible, preferably default, to avoid genAI.

I'm deeply disappointed that the Mozilla Organization has decided to add genAI to label tabs in Firefox. Even if I didn't have ethical concerns, I would still be disappointed at the bogged-down performance and genAI hallucinations that make this change categorically a downgrade.

I respect other users right to do things I find harmful, and the Organization's authority to make decisions. I treat genAI much as I treat smoking, everyone gets to make their own choices, but I have the right not to be exposed to second-hand smoke. Having genAI options default to on is like having somone blow smoke in my face, and when they can't be turned off, it is like having an acquaintence who insists on smoking in my home: I won't have them over (use their software) any more.

I'm in the process of kicking the people who smoke in my house out, and minimising my exposure to "second-hand smoke" (unwanted genAI). I've been a Mozilla user and proponent since the Organization was founded, and was a Netscape user before that, so I don't want to lose an old friend... but I am looking into other options.

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 posted this and was told it was ;posted, but then I got a not found error when I tried to view it, so I'm trying again.

I set a site to use firefox as the default app for ftp not realizing ftp support was removed from the browser. I have been trying to get the dialog back that will allow me to change it. I downloaded filezilla to use for ftp. However, I am unable to get the dialog back that will allow me to change apps.

Can someone help me get the dialog back? And, before anyone suggests it, resetting firerfox to the default settings is not an option.

There seems to be no rhyme or reason as to what Firefox keeps in the address bar drop-down, sometimes websites I visited once for a specific reason will stay there for literal months, and websites I go to often don't show up at all, or vanish after a few days (during which I will be actively clicking on them, no less).

I know it's probably a bit weird, but I actually like keeping several specific websites in the drop-down menu, it makes it easy to navigate to them without cluttering my bookmarks (any more than they already are). How do I keep specific websites in the address bar's drop down?

The keyboard shortcut to take screenshots [Ctrl + Shift + S] used to work a few weeks ago but it has stopped working for quite a while now. Doesn't work on any site, I can only create screenshots by right clicking and pressing the button manually.

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?

The font size in "Manage Bookmarks" is way too large, both in the sections list menu on the left and the list of bookmarks. I checked my userChrome.css file as well as the layout.css.devPixelsPerPx entry in about:config and there's nothing there to explain why only the "Manage Bookmarks" text is so large.

It's possible I changed a setting somewhere that's causing this. But I'm stumped re: what setting might be controlling the font size in only that UI. All other Firefox text sizes are good.

Thanks to anyone who knows where I should be looking

Firefox 134.0.1 (64-bit) Windows 10

Within Tool Settings create an option to choose one of the current six choices to become the default view. Currently "General" is the only default view upon entering Tools,Settings. As is with me I suspect the most revisited choice within Tools, Settings is "Privacy & Security". Would be immensely pleasing if I could select "Privacy & Security" as default view when entering Tools,Settings .

Please return my Computer to using Firefox default as my browser as it was 2/01 /2026.Ive tried several times to do this w/o success . I was using windows 11 and have been trying to get rid of MS365 which I never used but have been charged for a solution , but have been blocked and refused cancellation after they asked me to change my email address and PW . Insanely confusing !
