Firefox Community Forum

For the past week, I've been trying to set Firefox as my default browser on Windows 11 Pro (I've been using Firefox for years), but after restarting, the Edge browser reappears, even for PDFs (we use Adobe Acrobat) and Paint for TIFF and JPEG files! It's outrageous that Microsoft is forcing users to use Edge. This never happened to me with Windows 7 or Windows 10. I'm completely dissatisfied with Microsoft's policy of forcing users to use Edge! I've tried configuring regedit, gpedit, taskchd, etc., in a thousand different ways, and after restarting, the intrusive Edge returns! Is there any way to prevent this? Mozilla should fight this! It's unacceptable that we have to be tied to Microsoft's monopolistic whims!. Do you have any solution? Thank you very much!! Leonardo

Здравствуйте! При установке параметра "Настройки - Основные - Открывать Firefox автоматически при загрузке компьютера" в реестре создается запись HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run - Mozilla-Firefox-E385C0CFD98A494C: "путь-к-файлу\firefox.exe" -os-autostart Что за параметр командной строки -os-autostart? На на сайте поддержки Mozzila не нашел, ни интернет не подсказал. Я понимаю, что это автозапуск Firefox при запуске Windows. Но что конкретно делает данный параметр?

It was nice when FF was simple to use....unimcumbered with all the options...like the latest...profiles.

Why? It's getting to be as complicated as E and C..you don't need all those options - that's why I use FF.

Get rid, or allow the user, to pick and choose, and dump the unwanted stuff from cluttering the tool bar and other options. Just a suggestion that can be made to FF any longer. Use to be they'd welcome feedback.

When I press F12 to use the developer tools and try to change the width of the panes by click and drag the divider there now seems to be a limit to the panes width that was not there before. I'm not sure with what version I stated to notice this. I use to be able to drag the right hand panel fairly far over to the left and could take up about 75-80% of the width of the developers window. Now I'm guessing that I'm able to drag the right panel to a max width of 35-40% for some reason. I have not changed anything in the about:config page. I'm not sure why I can't drag the right panel to cover the 75-80% of the window that I had been able to do.

Is there a setting in the developer tools or on the about:config page that sets the max width that the right hand panel can be dragged to the left?

Hello,

I am dealing with a quite frustrating issue, and I literally cannot do anything to stop it from ruining my messages.

Whenever I manually type in WhatsApp Web or AI chats (like ChatGPT or Claude), Firefox completely hijacks my text box. As soon as I start a line by typing "1", a period, and a single space ("1. "), the browser forces my text into an auto-formatted numbered list.

This isn't just unhelpful; I see it as a genuinely harmful feature. The formatting it forces on me is weird and broken—it frequently adds massive, irrelevant paragraph gaps between list items, completely messing everything up.

I am completely stuck because standard fixes do not work:

If I press Ctrl + Z to undo the auto-formatting, it also deletes the space I typed.

I am not pasting anything; this happens the millisecond I type the spacebar from scratch.

It feels awful to have my manual typing hijacked like this. Users should be able to type a simple number and a period without the browser transforming it into a broken HTML list.

Is there an about:config setting or any way to completely disable this auto-formatting feature so I can just type normally again?

Thank you.

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?

Over the past few updates, I’ve noticed an issue with Firefox where it no longer restores my previous session when reopening the browser.

I normally keep four tabs pinned and about five additional tabs open for browsing and work. In the past, I could simply click the X to close Firefox, and when I reopened it, all my tabs that are pinned and unpinned would automatically come back. Recently, this stopped happening. Now, if I close Firefox, it opens with a fresh window instead of restoring my previous tabs.

I’ve already checked the setting under General/Startup, and Open previous windows and tabs is enabled. Because of this issue, I avoid closing Firefox entirely, since rebuilding all my tabs each time has become a hassle.

Is there a way to fix this? Any suggestions would be appreciated.

Thanks :)

When copying and pasting from one application to another, by using Ctrl + Shift + V to paste without format to Google Docs, I keep getting a "Paste" pop up that I've never gotten until now. It keeps getting in the way and I don't see a way to remove it.

It's making copying and pasting very difficult and is driving me up the wall.

Ctrl + scroll used to zoom exactly 10% (in or out) now with 1 scroll, the page gets zoomed in at least 30% but it's not consistent. right now, I tried CTRL+scroll up and the zoom went up to %133. I'd appreciate your assistance.

ps, IDK if it's related but I just updated Firefox to version 150.0

Thank you

I despise ai in every use and way with a passion. Now, it gets spammed everywhere on this browser, with no apparent way to disable and/or remove that filth. I don't want to see it, ever! Why is it even on by default??? I don't want "chatbots", "Ai assistants" or any of that shit at all.

the go back to previous page shortcut is annoying and it kept messing with my work and I want to disable it I use touchpad and accidentally goes back to previous page all the time and sometimes I have to redo my unsaved work because of this. Please disable this arrow in a blue circle thing

When I inadvertently press CTRL + R when entering text, it is VERY frustrating because the window refreshed and I loose all of what I typed! Is there some way to disable the CTRL + R combo so the window does not refresh?

Thanks

How can i change bookmarks menu so it will close after choosing. Ive searched and only found option to stay open, (Option to not close menu when opening new tab)... Not what im wanting, I want to open bookmarks choose and have it auto close the side bar of bookmarks. Maybe even auto closing the link folders opened. Windows 11.

Hey,

in new version of Firefox saved on PC value of filter (devtools.netmonitor.requestfilter) in file: prefs.js. How to autoremove this value after closeing browser?

Thanks!

Anytime I open Firefox that pop-up shows, I don't want F-fox opening every time I start PC but there's no option to get it to go away otherwise, or at least that I can see.
