Firefox Community Forum

When logging in to a website that I use many times every day all day, all of a sudden I log on and all I get is a blank white screen. I have tried clearing everything, restarting Firefox, removing Firefox and re-installing it, rebooting the computer, starting Firefox in the safe mode but no change. The same problem shows up on three different computers on two different networks with two different ISPs. The website opens normally on Edge and Chrome. I would prefer to be able to use Firefox. Using version 139.0.4 (64-bit) on all three computers. I would really appreciate any help that is available.

Today, when I went onto Vanguard, at the top of page it said my browser is not supported. However, Firefox says it is "up to date." It had already been changed to 115.24.0esr, as my macbook uses 10.13.6 High Sierra. Firefox says I am good and supported until August 1, 2025, but I am still getting the non-support message on the Vanguard site. Who is right?

Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

When I copy a post in X from Firefox into a text file, it loses formatting, but when I copy the same post in X from Edge into the text file, it keeps formatting. Why?

I just acquired a new Windows 11 computer, and I have installed Firefox. My old computer quit suddenly. I am trying to find the Firefox file location. There is no Mozilla or Firefox folder in "Program Files", "Program Files (x86), "Downloads", "Users/Appdata/Roaming", or any other location that I have thought of. I want to bring in my bookmarks from my old computer and I only have access to the files in the "Users" folder.

Where might these files be?

Hello: FF 140.b9 64b w11p. Are there ANY search engines (not nec browsers, just want to do a search in the address bar or search field) that do NOT go to an AI site to search? I want to minimize my use of AI technology, which uses extremely environmentally costly data farms. Thank you.

hi for some reason twitch.tv or some other websites will no longer play videos on my pc and i have no idea why, firefox works fine on my laptop

Hi, when I use YouTube.com and i find this on "https://www.youtube.com/results?search_query=blue+connection+touch+the+sky" I get this popup message ""This page is slowing down Firefox",etc.etc. What happened to the browser? Thanks!

so, basically, if i walk away from my computer for a few hours and firefox is open, I come back to the original window, plus a window for about every hour that i was away. all the new windows are just sitting on the homepage, but this only happens when a keyboard is connected as far as i can tell.

any keyboard by the way, i have now tried it with 12 different ones.(6 different manufacturers at least)

i have tried to refresh firefox, i even went so far as to do the "reinstall but keep my file" thing for windows 11, uninstalled and reinstalled firefox, deleted all the local files, cookies, etc, signing out of my account on the browser, malwarebytes said i didnt have any problems with my system.

I have even tried to figure out how to reset the http and https default to none in windows 11 to attempt to solve this.

the only thing that works so far is to not have a keyboard connected

any help would be great :)

I'm unable to access GroupOn from my laptop while using FireFox browser. When I attempt to log on using my Email user name, a message that states "ACCESS DENIED" appears. I have followed the steps to clear the cache but doesn't correct this issue. I'm able to access using my email user name using an alternative browser but I prefer FireFox. Currently running Windows 10. I receive emails from GroupOn using the same account that I attempt to log on with and receive the "ACCESS DENIED" response. Any knowledge would be appreciated
