Firefox Community Forum

When using any Microsoft 365 product on the browser I keep getting a prompt to "Please sign in" although I am already signed in. I can click the Sign in button and a about:blank page pops up for a split second. Then within a half hour or so, it will pop up again. I deleted my cookies but the problem still persists. Does not happen on other browsers.

Hi - Firefox placed an 'Old Firefox data' folder on my desktop and I am unable to delete it. I'ver tried third party apps, logging in as administrator, command line delete, uninstalling FF but am still stuck with it and my network settings are wrecked so I can't re-establish connection to the internet on that machine. Anyone with any suggestions as to how I get rid of the 'Old Firtefox data' folder ? Many thanks...

Firefox stopped working on my computer. Every time I try to open it I get an error message that says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I tried to uninstall and reinstall with no success. Our IT dept tried as well and nothing we have tried has resolved the issue. Thank you for your help.

Hi,

Not sure if anyone else is reporting this but ever since the last update - 140.0.2 Firefox Release, June 27, 2025 - many of my general sites, yahoo, news, company sites that I use everyday, do not load. I have to use Private Browsing, keep refreshing or change URL for the site to load. Anywhooos, I do appreciate you guys! keep it up!

Hello! After a clean install of Windows 11 24h2 Pro, Mozilla Firefox is unusable. It takes about 2 minutes to load a page which is abnormal. I remember I had the same issue when I first installed Windows 11 23H2 Pro and that was resolved somehow but it was 2 or 3 years ago and I've no idea what the solution was back then. I've tried some basic stuff including Test suggestion which of course didn't resolve anything as almost all of them are referring to cleaning cache, reinstall Firefox etc and it literally has nothing to do with my situation. Any solutions?

I believe this problem is caused by a false crash recovery loop, every time I open firefox it'll close again and then give me an annoying red striped address bar. I'm sure its not my extensions because I only have Ublock Origin installed.

In Chrome, for example, if you type "maps" in the address bar, it will autofill to "maps.google.com", which then redirects to the correct URL, "google.com/maps". Initially, it doesn’t do this, but if you do it repeatedly, Chrome eventually learns and sends you directly to that URL when you type "maps". The same happens with "gmail" or even just "gm", which redirect to "gmail.com" or "mail.google.com". Does Firefox have this kind of feature?

I think I browsed a reddit thread from a few years ago asking this same problem having something to do with autofill frequency which doesn't work, because the actual url is not, in the example of maps, maps.google.com and the url I want to enter redirects to it.

I have a problem that I cannot resolve for months. I'm always listening to YouTube I'm listening music while I'm working or I'm doing task on Firefox I used to have no problem I just Open YouTube and let it play on auto play and it goes no matter what. About 6 months ago I started to experiment some problems the video stop all the time even if I have a playlist going on like 50 song one after another it will stop once in a while for no reason. It pissed me off so much that I have to change my browser by default and I don't like other browser I use always Firefox with DuckDuckGo so when I'm trap to use other browser I get mad the only one that functions very good it's on edge Microsoft and seriously I cannot stand this… I'm forced to use YouTube only on edge it's the only place that it works no matter what it never stop. It used to be a little arrow in the bottom of the screen, a button that you can click on and off to Auto play or not, this button disappear it's not even there no more. This button Auto Play it's not there in Edge or Google Chrome but YouTube works for them not for Firefox so what is the problem it's not the setting is it YouTube that's got problem with Firefox? I don't know, it must be a way, a back door because I need to go back with Firefox I need to go back with DuckDuckGo. I'm pissed because I have to leave just because of that and that it's no compromise for me my music will pass before everything else. I don't feel like asking question to the community because it takes months before they answer you if they do. It's no customer service for Firefox or Mozilla whatsoever they don't answer you they don't talk to you they don't fucking care and this is another thing that pisses me off because they have a good thing going on but they don't care about the people. This was, this is what I did so far: Disable Hardware Acceleration "Performance" section.

I unchecked "Use recommended performance settings."

I unchecked "Use hardware acceleration when available." Clear Cache and Cookies I cleared the cache and cookies preferences privacy: Under "Cookies and Site Data," I clicked on "Clear Data."

Extensions about:addons I disabled all extensions to see if the problem persists… nothing happen YouTube I used YouTube in a Private Window … nothing happen YouTube Playback Settings I changed the video quality … nothing happen

Developer Tools for Network Throttling Maby using the developer tools, I can check for network issues? I didn’t try yet Reset Firefox I Refresh Firefox to restore it to its default state… nothing happen I uninstalled it and clean the registry. I reinstalled it. …nothing happen I ensure that you I’m using the latest version of Firefox: Yes My laptop specifications: Device specifications Device name: Fatcatbasse Processor: AMD Ryzen 7 5800H with Radeon Graphics 3.20 GHz Installed RAM: 64.0 GB (63.4 GB usable) Device ID: 8EDED38D-1047-40B4-8AIF-C2361C5E5841 Product ID: 00330-80000-OOOOO-AA797 System type: 64-bit operating system, x64-based processor Pen and touch: No pen or touch input is available for this display

Graphics Drivers I ensure that my graphics drivers are up to date. They are Testing Other Browsers I already mentioned that Edge works well Google Chrome also So you got an idea what I can do maybe shooting with a gun on the computer? Maybe pouring bleach or fuel on the keyboard? Maybe that work.

Why do searches default my home location to Northern Utah, when I live in Central Utah? How can I get Firefox to use my actual home location as my default location for queries.

It would be cool if you guys added a display to control the volume of a certain tab (like YouTube that people often use to play music while doing other things) AND add a feature that when a new media starts playing it stops the other one (like on Opera GX, the browser I came from). This would be really helpful and immersive since the user wouldn't have to deal with sounds collision and focus on his thing, not interrupting his flow to mute a music or a podcast or whatever. Also if you guys could add this feature, let the users choose between two options: pause (which completely pauses the background media) or fade-to-mute (which quickly fades the background audio until it is completely muted, but not paused. When the principal media stops playing, it will fade in again).
