if I load 2-3 YT videos in tabs, the playback stops, changing tabs takes seconds, and also slows other applications down

After seeing so many problems with ver 89 reported here, and with my own font display problems, I still forgot to remind my wife not to update firefox on her pc.

So, she updated, started using, then firefox crashed. After killing task, firefox loaded up on a white blank window. Troubleshoot mode or whatever also gives a blank, even after restarting windows.

Uninstalled 89, downloaded ver 88 and installed. Had to say goodbye to her bookmarks, saved login etc. To my horror, when I went into options to disable auto update, it was already downloading 89! Even after changing it and exiting firefox, it still updated to 89!

Uninstalled 89 and reinstalled 88 again. Disconnected internet before running firefox so that I could change the update setting first. What a hassle. Can someone with powers here tell firefox devs to not beat the purpose of reverting to previous versions...

Been a loyal Firefox user since the time of Netscape... Really sad to see another very problematic version... Hope the mvp volunteers and top contributors here can compile our issues and submit to the devs...

None of my pages load and I get this error message:

PR_END_OF_FILE_ERROR

This continues to happen and I really need it fixed please!

I end up having to use a different browser when I prefer firefox.

I have emptied my cache, refreshed firefox to default, checked my security settings, not sure I have ads or ad blocking if I do I am not finding it. I did disable some protections to try and get things to work to no avail; which I don't prefer.

I believe this issue is on your end because this happened a few days ago, then things worked, and now they are not again.

I have read many of your articles and don't have any more time to waste to try to fix this. It has been exhausting and now I need you to fix this please.

I won't be able to keep using firefox if this keeps happening. It would be much appreciated if you would fix this.

Thank you!

A link to my previous thread: https://support.mozilla.org/en-US/questions/1339912

Recap: I was having what I believe were some kind of syncing issues, where none of my passwords would autofill, and I couldn't save new login information, and was getting logged out of websites that I would normally be perma-logged in to. At the same time, I have also been having connectivity issues where FF loses connection to my internet for around 5 minutes. Sometimes it would fix itself and other times I'd have to restart FF. Meanwhile, Chrome would run fine in the background so I know it's not my actual wifi but it's specific to FF.

I have tried the FF "refresh" and when that didn't fix it, I tried a full uninstall/reinstall which fixed my syncing/password autofill issues but not my connectivity issues.

Any other ideas? I'm super bummed about this because I've used FF for many years and been so happy with it and have convinced so many friends to jump ship from Chrome over to FF. But I don't have time to keep troubleshooting this and it's looking more and more like I'll have to switch over to Chrome if I want to have a normal workday without frustrations and interruptions.

After auto update to FF 89.0, access to long-time Fidelity account is intermittently blocked as a security warning, or causes DSL line to drop at submission of account security code, or displays account entry page as plain text, not std HTML formatting, or most often results in a technical error page saying try again later. MS EDGE works fine, no issues. This is the only webpage this occurs on. Fidelity has no FF reported issues on their end nor does my IP supplier. Using desktop PC, running Win10/64-bit, DSL line @ ~ 2.3 Mbps. Using the "Light Theme" which was auto set with 89.0. This plus the new bastardized menus will push me to drop FF since I can't afford endless hours to fix basic functionality with ea update.

Hello.

Since updating to Firefox 89, I have been experiencing problems playing videos shared on Google Drive. (The problem occurred in the Devloper Edition of version 89, and version 89 was released to regular Firefox without a solution. When I start playing a video in Google Drive, it plays fine for the first few minutes, but then suddenly the video stops and the video screen goes black, and there is no response when I press the play button. The only solution to this is to reload the web page, but this is very inconvenient as the video stops in the middle and when you reload again it starts playing from the beginning.

Sorry for my bad english. Thanks.

I use this workaround to fix tearing on my mediacenter powered by a intel baytrail hardware.

https://wiki.archlinux.org/title/Firefox/Tweaks#Enable_Legacy_OpenGL_compositor

until v88, it was working fine.

With v89, the setting layers.acceleration.force-enabled=true has no effect. The "about:support" page reports Compositing: webrender (software) whatever the value true or false.

I had to downgrade to v88.

Hi everyone!

When I browse the web with Firefox, it happens that the system becomes completely unresponsive. Some web pages seems to make Firefox using a lot of RAM and write a lot on the hard drive. I cannot actually say much more, because it not even possible to login in a console. The system is too slow and the console login times out... Firefox (or Web Content) writes wildly on the hard drive.

I used the Firefox provided by my Linux distribution (Linux Mint), but also the one downloaded from mozilla.org. The problem seems to be less frequent for the second, but it happend nevertheless.

The point is that this problem with Firefox happens sometimes, for example, when I forget the browser open on somehow demanding webpage (like in newspapers where there are a lot of media, graphics, and so on).

A point is also that I cannot replicate this "bug". If now I browsed the same pages that made the mess, nothing would probably happen.

I thought it had to do with the swap, but the system hanged both when the swap space was enabled and when it was disabled.

I saved a copy of the profile (and the cache) after the last crash, if they could be useful. The last time I had actually to force the shutdown of the computer, because there was no way to regain control over it.

Any ideas?

Thank you for your answers!

For about a week now, I have been having issues using netflix and youtube with firefox. I have tried answers provided in other questions, such as emptying the cache and clearing cookies - which works! But only until I leave the page or change what I am watching. Netflix is especially frustrating as it requires me to go to netflix.com/clearcookies every time I use it - which means I also have to re-log in.

I have no idea why this is happening and am getting increasingly frustrated. The problem appears in safe-mode (troubleshooting mode) and I cannot find a permanent solution. Any help would be appreciated!

Hi Folks, I am running firefox on my macpro 3,3GHz 12- Core Intel Xenon W Graphics AMD Radeo Pro 580x 8 GB, I am using an apple XDR display.

Every so often I experience a white flash, just within the Firefox window, not across the entire monitor.

I have tried a completely new and full install of Firefox but same problem.

I wonder is anyone had any thoughts or ideas  ?

I have two problems since installing Win 10 update KB5003637 on June 11. FIRST, I get the "Firefox is not your default browser" dialog box every time I open Firefox. Windows Settings shows that Firefox IS my default browser. I have restored Windows default (Edge) and re-set to Firefox, but I still get the "not default browser" message. SECOND, when I have Firefox open and click on a link in an email, instead of the link opening in a new tab, it opens a second, "generic" version of Firefox; one that does not have my Bookmarks or Passwords.

I'm not sure if this problem arose with the latest Firefox upgrade (I'm running MacOS 10.14.6 on an older MacbookPro) or has just appeared after a few days of use -- I think it's the latter. But I can no longer rearrange the sequence of tabs in a window, an absolutely essential feature. There's a contextual menu choice that gives me the option of moving a tab to the beginning, end or a new window, but that only helps in ~10% of situations. What gives??

Following a recent update to version 89, a previously stable Firefox installation is now almost completely unusable. Just getting to the point of getting to this page where I am writing this post has seen THREE Firefox crashes, as switching tab to my email so as to get the verification code for my mozilla account was seemingly too much for Firefox to handle. Viewing Facebook messages and scrolling up to see comments made earlier in the day sees the layout of the page completely screwed up (main content shifted to bottom right corner, scrollbar shifted elsewhere, part of the page blank) and at that point trying to switch to another tab creates a strange hybrid situation where some of the contents from both tabs is merged together and is then the only content visible no matter which tab is then clicked on. Using Google Maps works for about 30 seconds and then the entire page flashes repeatedly with every move of the mouse, before this triggers a browser crash. I can be reading content on a news website and suddenly the tab crashes for no reason, and in most cases the browser then crashes thereafter. Restarting the browser and the news page tab will be shown and begin to load but then immediately crashes. These are just some of the issues that have occurred within just the past 2 hours, but this is a cumulative effect as Firefox has been becoming increasingly unstable to this point after updating to version 89 earlier in the week.... No other changes have been made since updating Firefox, here has been no Windows 10 updates, no other applications have been installed or updated, no other software has been either added or removed.

I could run the previous version of Firefox for several days, leaving the computer running but idle for a few hours each day, and still come back and resume where I had left off without issue. Now with Firefox 89 it is struggling to even go 30 minutes without tabs or the entire browser crashing. When can we expct a fix, or is there otherwise a way to roll back Firefox to version 88 without having to do a full uninstall/reinstall...?
