Firefox Community Forum

Every 1 - 2 hours Firefox stops loading pages and I have to shut it down and restart it and restarting takes around 6 clicks on the icon to get it to start.

Also one time today I lost all my pinned tabs and had to manually restore them one at a time.

Using Ubuntu 24.04.2 and latest Firefox. Cleared cache but doesn't help.

Firefox detected a potential security threat and did not continue to nrega.nic.in. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

Firefox has been crashing several times an hour for multiple days. I have tried:

Changing/Upgrading RAM Reinstalling Firefox Resetting Firefox Reinstalling Windows Updating Drivers

Firefox 140.0.2 on Windows 11 All localization settings are correct (English / US)

I like to use the Inter font where I can due to its legibility, etc. I've used it as the default font in Firefox for a long time and I have Firefox set to not override fonts. Recently I've noticed some glyphs aren't getting rendered / chosen correctly. This is just one example (a message entry field on a forum) but I've seen it elsewhere so it's not just this page. See the attached images comparing Segoe UI and Inter.

Font issue or Firefox? I'm tempted to suspect the latter since I've used Inter all over the place previously without problems and being a font, once done it's done. I've also not seen issues in places using Inter.

Thanks.

I have all options enabled to save addresses and credit cards.

When I try to manually add a credit card, hitting the Save button does nothing.

When I use a credit card on a site, Firefox prompts me to save the card, I confirm that I want to save it, yet it isn't saved.

I really need help with a border around my Firefox on windows 10. I've tried every UserChrome workaround that I can find and it may be an issue at the system level. But I've never had this issue on any program.

-This issue is only present on my win10 desktop and not my win11 laptop. -F11 fullscreen DOES fix the issue but I don't really want it in fullscreen. -Displaying the titlebar also DOES fix the issue but I'd like it hidden. -I do have a second monitor, but I unplugged it and restarted FF. It's the same resolution. -It's not a profile or theme problem. It persists on new profiles and reinstallation.

Firefox on my Windows 11 machine does not display a bar at the bottom of the screen. This is a problem when a web page is wider than my display, there is not slide bar at the bottom to grab and pan to the right. I have not found a way to get the bar back. Is this intentional? Am I missing something?

Hi, When I play a YouTube video, there is no sound, then (I'm assuming) there is an update, and the sound returns until the next update, when the sound disappears. I have had everyone try to solve the problem, and even the tech guys don't have an answer, and yes, I get sound from Chrome. Also, when I download a YouTube it plays perfectly fine. Are you able to fix the problem?

I downloaded firefox and it worked for about a month. Now when I try to launch it, the screen flashes momentarily as though it were about to pop up, but then it does not actually open a browser window. I have uninstalled and reinstalled firefox more than once, I've tried a simple restart of the computer, and tried multiple different update methods (updated windows). Any suggestions?

Hi everyone, I use Firefox as the main browser for my iMac (Sequoia 15.4.1). Recently, Firefox has been incredibly slow. I'm able to boot up and open Firefox (140), but when I search for something or create a new window, it never loads. Is there a way to fix this? I can open the same websites on Safari, but Firefox is my employer's preferred browser. Additionally, my bookmarks are all saved on Firefox. Thanks for insights/ideas/solutions.

In early June 2025 I finally ditched Windows 10 for 11 and I've been a Firefox user since practically the very beginning of Mozilla.

Now, I notice that the "Restore Previous Session" button in the drop-down of the FF menu is missing. Additionally, I discovered late in the game that Mozilla DID listen to me and gave us the ability to "name" or "tag" an entire window in the browser. This was a HUGE boon to productivity as I'm constantly toggling from window to window to tab to tab.... Now, with the most recent update this ability seems to have disappeared....
