Firefox Support Forum

Firefox 86.0 (64bit) Ubuntu 20.04.2 LTS Gnome 3.36.8 Desktop: Intel 2 core E7500 CPU AMD RV710 Graphics Memory 3.8GiB Firefox entire display including menu bars covered with colored confetti which moves in response to mouse movement. Firefox Safe Mode is not affected. No other application on this system is affected. Effects all user log ins on this system. Action: Complete uninstall (purge) of Firefox and cache then reinstall--No Fix i.e no additional AddOns. I believe this uninstall/reinstall removed Firefox and downloaded a fresh copy.

I'm having a similar problem to other posts I've seen here at support.mozilla.org, but not exactly the same, and none of the solutions are working for me.

I was using my Firefox ("FF") for Mac v77.0.1 with many tabs across 3 windows (as I've done for years). I Quit FF, shutdown Mac, and when I restarted Mac and FF, the windows and tabs did not reopen (as opposed to always reopening just fine, for years and years).

I looked under the History menu, and the missing windows and tabs did NOT list in the Recently Closed Tabs or Recently Closed Windows, BUT it DID list tabs and windows that I HAD recently closed.

I went ahead and selected Restore All Tabs and Restore All Windows, hoping that maybe it'd somehow open my last opened windows/tabs, but not only did that not happen, but it didn't even open the actually recently closed tabs/windows it had listed. Then, the History drop down menu just greyed out the Recently Closed Tabs and Recently Closed Windows options under History.

NOTE: It might be best to next skip down to MY Reply to this post (solution??), and then up to my Update/Edit (down below), before continuing right here to read my efforts to solve this!

Luckily, I had just backed up my Mac right before shutdown, so I grabbed the sessionstore.jsonlz4 file from most recent backup, Scrounged it at https://www.jeffersonscher.com/ffu/scrounger.html, which produced an HTML that lists all the windows/tabs that I had open (including the Back-Forward History) before Quitting FF & Shutting Down Mac.

Then I followed these instructions I've seen many places: 1. quit FF 2. rename sessionstore.jsonlzr in my FF Profile to sessionstoreOLD.jsonlzr 3. copy sessionstore.jsonlzr (and next recovery.jsonlz, and next previous.jsonlzr) from my Mac backup 4. paste sessionstore.jsonlzr into the FF Profile on Mac (or paste recovery.jsonlzr or previous.jsonlzr, renaming them sessionstore.jsonlzr once pasted there) 5. open FF

Once I did those steps 1-5, it did NOT open any of my windows/tabs from previous session.

I even tried renaming my whole FF Profile from 2d7si5hi.default to 2d7si5hiOLD.default, and then copying the FF profile backup and pasting into Mac next to the old FF Profile. Once reopening FF, still no previous windows/tabs.

I even tried Trashing FF Profile 2d7si5hiOLD.default, before pasting in FF Profile from backup. Once reopening FF, still no previous windows/tabs.

I then did all the above with even older backups (from about 2 weeks ago). In THIS case, ONLY ONE of the 3 windows opens with lots of tabs (but not the other 2 windows of tabs).

I then updated my FF to v78.7.0esr, and went through ALLLLLL the above steps again, and the results were the same (unsuccessful).

I then tried creating a new FF profile, copying ALL contents from most recent FF profile backup and pasting into the new FF profile (per jscher2000's instructions - but without having done the Refresh FF - at https://support.mozilla.org/en-US/questions/1136981) .... again, none of the previous windows/tabs showed up.

SO - anyone know how to get my FF to show all the windows/tabs that ARE present in my sessionstore.jsonlzr backups? Am I missing some step(s)??

By the way, in both FF v77.0.1 and v78.7.0esr, this glitchiness is also happening:

• FF Preferences won't open
• Help > Troubleshooting Information won't open (except for SOMEtimes if I already have a new Window open)

Thanks much!!

UPDATE/EDIT!: Whoa. Weird. I just happened to accidentally toggle to my Mac Dashboard (which I rarely use), and underplayed beneath the Dashboard Widgets were THE THREE MISSING FF WINDOWS OF TABS - which I could toggle between there at the Dashboard. I toggled back from Dashboard to Desktop, closed the FF that was open and NOT showing the windows/tabs, then toggled back to Dashboard, and the FF windows/tabs were no longer there. THEN, I reopened FF, again no windows/tabs, but then a toggle back to Dashboard - and boom, there they are! Say what?? OKAY - so FF is accessing/seeing the windows/tabs, just not displaying them within FF, but, instead, as standalone items behind Widgets on the Dashboard. Does this give anybody any insight on what's going on and how to fix it (way above my head!)?

I'm using a Surface Pro 7, running Win10H. Firefox had a brief period when I first installed it where the on screen keyboard would appear and work, that stopped after a few hours and has not worked since. I fiddled with the settings on both Firefox and my surface, though nothing has changed. Un/re-installing did not help, thought it could reset something. Any fixes or advice would be greatly appreciated.

For clarification, the Accessibility Menu on-screen keyboard does work, but the tablet-specific larger keyboard does not function. It does open and type in other applications.

Some tabs crash at random. Cannot reproduce at will. Started happening ever since I've upgraded to a Ryzen 3600 CPU. RAM with the XMP profile passes the entire 2 hour-long 4 -pass Memtest86 without errors.

The crashes happen on all versions of stable Firefox and on Firefox Developer's Edition. They also occur if there are <10 tabs open as well as 100 tabs open. I have 5-6 very common extensions on FF stable (Bitwarden, Gesturefy, uBlock Origin, Facebook Container, Open Tabs Next to Current, Wikiwand, and the Stream Detector), but not a single extension installed on FF DE and still it crashes too.

Some of many crash logs: bp-87b13e5c-1bc5-4f68-864b-95d6b0210227 bp-1751032b-df93-404e-822f-c13020210227 bp-e7840772-f24e-439b-b56b-ca8c50210227 bp-629bbf6d-b007-4b4a-8b76-b2d5e0210227 bp-dd9c0c07-61bf-44a4-b5a6-9f4170210227 bp-07cf5b11-39c5-4802-a448-7e6920210227 bp-97139c27-1633-4bab-a876-1bc030210227

These are all just from today, and these are not even all of today's crashes.

System details: AMD Ryzen 3600 16GB DDR4-3200 RAM (XMP profile 2) MBO MSI B450 Tomahawk (latest Beta Bios v7C02v1H3 - happened also with stable BIOS, so I put the latest BIOS on if there are possible BIOS<-->RAM problems but still crashes remain) Nvidia GTX 1070Ti (driver v461.72) Windows 10 Pro 20H2 v19042.804

Any idea what's causing this?

I want you guys to fix the video playing on SvtPlay and maybe other sites too. So that it is not choppy anymore. I just played a video from the documentaries section on svtplay.se and it was choppy. The streaming of channels was not choppy though.

I use the latest version of Linux Fedora and Firefox.

Firefox 85.0.1 Ubuntu 20.04 suddenly just blank no pages render, no access to preferences nothing except the menu bar - I have tried starting in safe mode, refreshing firefox, deleting profile info, starting a different portable version of firefox 78.3.0 also blank. There is a message when started from the command line about multiple gpu's detected (there are 2 nvidia gpu's one of which is passed through to a guest kvm) Other browsers work fine on the system and firefox worked fine until recently other than stopping using firefox on this machine which I would rather not do I seem to be out of options (note firefox works fine in the guest kvm's) [GFX1-]: More than 1 GPU from same vendor detected via PCI, cannot deduce device [GFX1-]: More than 2 GPUs detected via PCI, secondary GPU is arbitrary

Hi all - having an issue with Firefox sync...

I have a Windows desktop, a Linux desktop, two Linux laptops and an Android phone...all running Firefox and signed into the same Firefox account.

I've got them all set to sync bookmarks, but I've noticed that I'll often add a bookmark, organize it into a folder on one machine and then it will either never sync onto my other machines, or it will simply sync into the Bookmarks Menu rather than into whatever folder I had organized it into on all my other machines...

Is there a way to get it working properly on all my machines?

Thanks!

I have noticed in my options section that I can specifically pick what I want. But, looking at it from a computer performance point of view (computer speed) which settings are best? In the browsing category what should I select? There are more than a few options there. Which ones do I need for good computer performance? And which ones should be not used? In the applications category what selections should I pick? There are currently many-many selections there. Are all of them needed or required? Would it be advantages to remove some? Hopefully someone can help? Thank you.

Hello. After updating Firefox on my Macbook, a website I visit now will not load, the message "transferring data" will appear and the status indicator looks like the data is loading, then when the status bar looks like its at 100%, it will start over and show "transferring data" again, and this keeps repeating indefinitely. This only happens when using an IPv6 address, it works fine with IPv4. This did not occur in Firefox 81.0.2. This also does not occur on other websites or with other browsers. I am looking at the notes for releases between 81.0.2 and 85.0.1 but am not sure what may have changed that would cause this. The website in question is a BMC GUI for a server I'm working on. If anyone has any ideas I'd really appreciate it. I tried the debugger in Firefox but not sure what I am looking for. I did set a breakpoint for caught exceptions, and the screenshot is attached if it helps any... Thanks!

I am using centos 8.2 with it's firefox 78.7.0esr (64-bit) I also have my home directory mounted via NFS using the automounter system.

In general firefox works fine in this configuration. However, when I get on Ebay and try creating a listing, firefox will hang when adding photos and/or moving the photo order. My NFS server will then start complaining about 'failed to contact remote rpcbind.

I try to close firefox and it doesn't It then will ask about a script running to long and offer to close. It won't I wait quite some time and it doesn't close About now the whole system is locked up and I may be able to get to the reboot menu I reboot and it won't because the process is hung. I usually have to power cycle to get things back.

I think if I waited for the automounter to time-out firefox may close at that time.

So the questions are: Is this supposed to work in an NFS environment? What is going on to cause the hang? Are there environment variables to move "some directory" to the local disk drive if that is the problem?

I sure hope someone can answer this for me. Thanks Warren

Hi everyone,

After the 85.0.0 update and still now with 85.0.1 and 85.0.2 firefox crashes. It's usually happened with clicking a link that'll take action outside of firefox (not a url link but a download attachment link in gmail or a print link). I've also had it happen with placing links from the search bar to the bookmark bar, and just recently opening up the 'show all bookmarks' window.

It'll hang, i won't be able to click anything, and then it'll give me the 'close window' screen. It's never fully crashed and given me an error message. I start up firefox again, restore the session and everything is back to where it was.

I've tried refreshing. I've tried creating a new profile. I've tried uninstalling and downloading 85 direct from mozilla. Nothing seems to be working. I'm going to see how it does for a bit in safe mode, but all the add-ons I have I've had way before the 85 update and all of them are recommended by mozilla.

I'm all ears (eyes?) for solutions!

I installed Firefox on a MacBook Pro 13" (Mid 2012) with MacOS 10.15.7 Catalina. Before closing Firefox for the first time, I carefully opened settings and ticked "Restore previous session", under "Start" on the "General" settings page. But when I opened Firefox again, there were no tabs, just a "Welcome screen" as if it was the first time ever I use Firefox! This is extremely disappointing! I am really shocked! I had never thought that Firefox would screw me like this! I have been using Firefox on Windows and Ubuntu for many many years! I can add that it is Firefox 85.0.2. And now it updated itself to 86.0.

Hi, QR-codes and images are not always visible and replaced by some random weird image (see attachment). If you recognize this problem and know how to fix it, please help me :) Thanks!

Best regards Martin

Hello,

I had a 300mpbs connection for download, but was never able to get past 200mbps. But now today, on installing a 1gig connection, I still cannot get past 200mbps. The installer blamed it on my PC's network card. But I just ran the same speed test with Microsoft Edge 64-bit, and I was able to get past 600mbps. So clearly, this problem is isolated to Firefox.

I am using the latest Firefox 32-bit. I have no addons installed. I am running Firefox on Windows 7.

After typing this post, I thought the 32-bit Firefox was probably causing the issue, so I installed the Firefox 64-bit, and the speed increased by 50mbps to 250mbps.

Thank you.
