Firefox Support Forum

OK, I was using a very old version of firefox previously and restore previous session worked perfectly. If my computer crashed, when I rebooted it, the "trouble finding pages" message came up, click to restore session, and everything came back.

Then.... I upgraded to version 72.0.2 (64 bit)

Session restore no longer works, or at least not the way it should be working.

If I had say 20 windows open when the computer crashed, when I finish a reboot and start Firefox, I get the "trouble finding pages" message, and I click to restore session as before.

Anywhere from 2 to maybe 5 windows will restore. The rest are gone.

I suspect it has to do with the fact that there were now multiple "instances" of firefox running in the task manager, and what's happening is that it's restoring the windows in ONE of those previous instances, but not all of them.

It gives me the impression that the session restore function isn't tracking all the windows open in all those separate instances, but rather it's only tracking one instance.

Any assistance would be appreciated.

With every update, Firefox becomes more and more unusable. It's been 20 minutes so far on this morning's session, but the tab won't open. And Options won't let me clear data as those tabs are dark. It's hard to be nice when I read these same complaints in forums all over the internet. It's only getting worse, and the recommendations are always the same -- clear your cache, remove extensions, blah, blah, blah. No, nothing works! It's time to blow it up and start over. Not to mention that it's always crashing or not responding. It's just about as useless as Edge and Chrome. What a pity. (Oh, I just noticed -- 27 minutes later -- that the Clear Cache tab is now active. Better late than never, I suppose.)

I noticed ever since I updated to FF ver 85 I started seeing screen tearing when scrolling. This is most noticeable when scrolling through a list of videos or pictures. This only happens on Fire Fox. I do not experience this problem on Chrome. I have already disabled Hardware Acceleration. Made no difference. I'm currently on FF version 86.

Anything else I can try to resolve this issue?

Hi Guys 'n Gals, As of today, I am unable to log into the Australian Tax office Business Portal or Business Services (BETA) through MyGov using Firefox browser. I can log in through Edge, no problem to both. I've cleared histories, cache etc on Firefox, and it is up to date. I've logged out, and logged back in. When I attempt to enter the email address to log on to ATO using Firefox, I can type the address as far as ".com". The moment I type ".", I lose the entire address, except for the ".". I don't get to the "com.au" part at all. I've contacted the ATO, they have no updates at all regarding issues with Firefox. We are getting close to Plan C (Sledge Hammer LOL). Any and all help gratefully accepted, I do not like edge....... Thank you Trina

Hello,

I've been getting an error for some time now. Firefox tabs suddenly crash (usually media tabs with video, like Twitch or video conference sites) and I can't seem to find a solution. But most importantly, many videos or live streams show graphic artifacts. You can check it in the attached screenshot). I have tried many things to solve it, but none worked. This is what I tried:

• Changing cables and monitors.
• Disabling extensions and plugins.
• Disabling hardware acceleration.
• Installing Firefox from scratch.
• Installing an old version.
• Installing Nightly.
• Removing the GPU. The issue persisted with a different video card and with integrated graphics. So the GPU is not the issue.
• Trying using another OS. I thought my Windows install might have been corrupt, but it also happened in Ubuntu.
• Trying other browsers. I tried Chrome (which resulted in the issue as well) and Edge (which surprisingly did fine, it's my only solution right now).

I would love to keep using Firefox but it's a pain to watch media like this. I don't know if the issue might be from the motherboard or another component. Between the crashes and this I can't use it normally.

I can try providing any details needed to solve the problem. Could you please help me? I don't know what else I can try.

After update from 68 to 78.8 my Firefox do not load web pages. It still loads local files (file://) and LAN sites (http://192.168.x.y/). But on attempt to load something like Google it shows just empty page and Network console shows zero bytes download (see image attached). I tried to reinstall it, removed ~/.mozilla, network.dns.disablePrefetch=true, network.dns.disableIPv6=true. Nothing of that helped. Chromium on the same machine works fine.

Why Firefox Taking Resource Without Even Opening Multiple Tabs ,At Startup Browser Starts With 60-70 CPU Usage And Even If Close The Browser It Still Takes 60-75 Until I Close It From Windows Task Manager,Attached Some Screenshots Check It You.

Each time Firefox has crashed, I've submitted the report. How can I prevent this?

This happened every time 2 weeks or so ago. I cleared the cache and it seemed to work temporarily. I've run Firefox for a number of years now and only within the last month has it given me problems with Plex.

So, for about a month or so now I have been experiencing random freezing in Firefox on my home PC running Windows 7 (I know it's outdated, it's by choice). I'm pretty certain it started after a specific update, but at this point can't tell which one.

Here's the behavior itself:

Firefox completely freezes and soon after the window turns white and a 'Firefox stopped responding' dialog pops up. After I close Firefox, I am able to restart it normally. However, at restart, it says 'Oops, there was a problem restoring your session' but then successfully restores the session if I click the button or select the option from the History menu (however, this does not always pop up - see the 'what I tried section').

When it happens:

1) When interacting with input forms such as login and password forms. Seemingly happens more often with forms that have previous input saved for them, but I'm not sure.

2) When opening new windows (notably NOT new tabs) such as when opening a private browsing window, bookmarks window, download history window or when using the picture-in-picture option on Youtube.

How frequently it happens:

The frequency appears to be random and not specific to any website. It most often seems to hapen after about an hour of browsing, but can also happen immediately at restart or go longer without freezing. Interestingly, disabling Ublock Origins seems to dramatically decrease the frequency of freezing, but does not eliminate it completely.

What I've tried so far:

1) Looking for problematic extensions. Running in safe mode seems to prevent the issue, so I started disabling extensions one by one. Ultimately though, even with all extensions disabled outside of safe mode, the issue persists. As noted above, it seems to freeze less often when Ublock Origins is disabled.

2) Tracking memory and CPU usage. Nothing abnormal there - I have 16 GB of memory and Firefox rarely goes over 5.

3) Refreshing Firefox. This did nothing except cause the 'Oops, there was a problem restoring your session' tab to first start appearing. Before the refresh that didn't used to happen at restart.

4) Disabling hardware acceleration. No effect.

5) Removing bookmarks. I had a very large number of bookmarks saved so I deleted a bunch of them. No effect.

6) Deleting the places database. No effect.

7) Deleting the session restore files. This has been the most interesting option. Deleting the session restore files DID stop the freezing... until it came back again in a couple of days. Interestingly, when it first came back it was not accompanied by the 'Oops, there was a problem restoring your session' message at first, but eventually that started appearing too. This gave me the thought today that perhaps this is caused by a website somehow 'corruping' the session data. I was going to delete the session restore files again and start looking for the offending website, but puzzlingly, this time deleting the files did not stop the freezing.

I just recently moved from Win 7 to Win 10 (x64). The Win 7 install was getting unstable and I was getting blue screen crashes a couple of times a week. I suppose it's possible it was Firefox related, but Firefox seemed to work OK.

Since the upgrade, Firefox has been unstable in a very odd way I haven't seen before. I've been using Firefox and its predecessor Netscape since 1995 when I was using a beta version of Netscape.

Sometimes Firefox will crash and then refuse to restart, but most of the time the problem is I can get it to restart, but then if I close Firefox and try to reopen it, it will refuse to restart. If I copy over a backed up profile it will usually start at least once and may run OK for a couple of days. But when it crashes, I can't get it going again without copying over a backed up profile. Though that can be hit and miss too. Sometimes a backed up copy that worked before won't work, but another backup will.

When I upgraded I was on, I think 70.0 esr, but I upgraded to 78.8.0 esr (both 32 bit) trying to get it stable again. I tried installing 78.8.0 esr x64 and i was able to quit and restart, but it crashed and refused to restart a few hours later.

I tried Safe Mode and it starts in Safe Mode, even with a bad profile, but when I turn off all add-ins in Safe Mode and try to start normally, it won't start if it's not starting. Hardware Acceleration is off (it's been off the entire time).

On the most recent crash I deleted the profile that crashed copied over the last working profile files, but it still wouldn't start. I then went back to the Win 7 installation profile, copied over the crashes and datareporting directories of the profile and it started.

I've tried copying small pieces at different crashes and copying over something that worked the time before sometimes works, and sometimes doesn't.

Has anybody ever seen a problem like this one? And if so did they manage to fix it?

i have used Firefox for years never an issue.

3 or 4 days ago the audio stopped working for no reason. the audio works fine on google chrome, Microsoft edge, video files but not on firefox?

autoplay is set to "allow audio and video" a youtube video plays but no sound. i did notice if i set autoplay to " block audio video" nothing happened, the video played yet no audio. volume mixer shows Mozilla firefox but no sound. what is going on, this is beyond me.

This has been going for a couple of days.

I have tried starting in safe mode, didn't help.

I have tried disabling JavaScript, didn't help.

Two "main sites" affected, Feedly and Gmail. Feedly had this problem but it disappeared after a while. Now Gmail is having problems. I can move around and read mails but not respond to them.

Other sites affected "seems" to have in common that they are blog-type, perhaps like WordPress or similar.

I have a Windows 10 computer with the same browser setup and there have been no problems there so far.

The version is 86.0.1 (64-bit).

I'm not technically advanced so please be gentle with me.

Nonostante ho disinstallato e reinstallato e provato in modalità provvisoria il problema persiste. Vi invio ID segnalazione del crash bp-7945bba9-d1e0-478e-b2d0-d74c60210322 Cordiali Saluti.

I am running the current version of Firefox 86.0.1 and MacOS Big Sur 11.23. More often than not when trying to open a webpage I get the spinning colorwheel and the page does not load, after about 5 minutes the spinning colorwheel goes away and Firefox is dead. I must kill it and restart. This also happened frequently before the latest MacOS update.

This started today, I wanted to watch YouTube videos today and they were stuttering like crazy. Every 2 seconds it'd stop and start again and there was no buffering so I am sure it is a FireFox problem. Will this be patched?

Suddenly I am no longer able to launch any internet searches. Using google (normally) or bing I receive one of two messages, "Deceptive site" warning or "Server not found"??????????????????????
