Mozilla account in Firefox PC browser always asks to re-login every 1 day. This problem appeared after updating Firefox from version 119 to 120 and 121.

As in the image below, "Account Disconnected" and a triangular warning appears in the Firefox menu bar. I can't access any sync data like passwords, bookmarks, plugins if I don't re-login.

I only use this mozilla account on 1 PC.

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

Hi, I have a problem starting yesterday. When I video chat with anyone using Firefox on FB messenger they can see me but I cannot see them. Only a black screen where they should be showing. I have tried everything from uninstalling to different settings. I have made sure also that permissions were set correctly. Also it has been giving the error "slowing page down" or what says. Nothing helps. Now if I use Edge or phone it works just fine and we can see each other. This has never happened before. Also, the messenger games wont work on firefox either, but will on others. Please help if possible or tell me how.

Thank you

I'm having problems with Firefox using 75% of processor capacity. In "top" I see many instances of "Isolated Web Co".

At the moment of this screen shot the processor is not overwhelmed, however, it will sometime jump up to 75% and the system will seem to freeze.

What is the "Isolated Web Co"? I'm thinking a virus.

Thank you.

Hello! I need some help. Every since 4-6 months ago, Firefox has been extremely slow when I boot it up at first, with some page load times taking more than 10 minutes. Some fixes have seemed to work, but they never work permanently. From my testing, it is not the result of any extension and the issue persists in troubleshoot mode. What has not helped my testing is that, after enough restarts of Firefox, the problem goes away and web pages load quickly, so this has caused some false positives. Has anyone else had a similar problem they were able to fix? Should I try uninstalling Firefox and reinstalling it?

Trouble saving downloads

Prior to about a month ago, downloading worked as expected: - click a link - the save to... dialog opened - choose the folder - the download is off and running

No more. For about the past month - click a link - wait for a long time with FF frozen - the a wheel starts rotating - after a full minute (or more) the save dialog appears.

Something has been broken in the mad-dash to push updates. It's fine for browsing, but the, you need to download. At that point you wish you were using a different browser (any other browser, in fact) since FF is the only oe that has this problem. Downloading works fine in a 8 chromium browsers that I have and in the 5 FF clones (like Waterfox)

It's just FF that's broken. I can no longer afford to set it as default because of this. The others are not perfect (WF won't activate Pocket, foe example) but downloading promptly is critical.

When I open a locally downloaded pdf in firefox, the background is displayed as what was previously displayed on that portion of the screen, and scrolling simply overlays moved text over what was previously displayed. Does not appear in screenshots. One of the images shows what the pdf looks like prior to scrolling, and one after.

Last night, when I got home from work, my Firefox browser wouldn't let me make any Google searches or log into my Google account. It just keeps coming up with the end of file error. I've refreshed Firefox, created a new profile, turned off Proxy, uninstalled NordVPN, and even tried to uninstall/reinstall Firefox. After refreshing, I can sometimes search with Google for a little bit until I try to log into my Google account or navigate to Gmail while not logged in. It also won't let me access Yahoo.com, it seems. It will do random websites, though. For example, I entered the url for a video game forum I've browsed in the past and it loads that okay. Any suggestions? Do I have a virus or something? I honestly can't figure this out.

So to cut it short, i have an issue with not just firefox but almost all other browsers too. I have tried Firefox, Chrome, Opera and Edge. Both Firefox and Chrome will instantly close when i open them. As in, the window will open and immediately close after barely half a second. This has happened with Chrome and Firefox, yet Opera and Edge dont seem to have this issue. I am a Firefox user normally so this does make it a little annoying. Any ideas on why that is?

I use a MacBook Pro. I recently created a new profile for Firefox (for work purposes) and set it as the default profile, because I'm trying to get off Chrome entirely. The preexisting no-longer-default profile contained all my "personal" data - bookmarks, extensions, etc. Continued using both profiles for about a week with no issues. Last night my MacBook updated and when I reopened Firefox, the new default profile was fine, but when I went into about:profiles and launched the secondary profile in a new browser, it was completely empty - no history, no bookmarks, no extensions, nothing. That's at least a year's worth of data completely gone. I've looked through support articles and past folks' questions and am just completely lost as to how to restore it or what went wrong. If it's not possible to restore that data, how can I at least prevent this from happening again? I've very much lost trust in Firefox profiles because of this. Help please?

Running on an M1 Ultra Mac Studio, Firefox struggles to play 4K videos in recent days where it would've normally performed fine. I've never had troubles watching 4K YouTube on Firefox, until the past week or two. There are no other applications running, and only the one tab open in Firefox. Just a regular 4K video. Why won't it play properly? Why does it start buffering randomly when I can see my network is just fine? Why does it just randomly skip 10 seconds every minute or so while playing? This exclusively happens on 1440p or 2160p (4K). Please fix this ASAP.

Firefox 120.0.1 Memory Leaks, Windows 11 & 10, not a new issue

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.
