In the last week I've continually had the error message PR_END_OF_FILE_ERROR appearing in place of various websites. There's no consistency - one day a website can load fine, the next I get the error message, the next day it'll load fine again. And the problem seems to be getting worse... It's driving me mad! Please help!

On ubuntu 20.04, the snap version of firefox can't play some videos. Some youtube videos will play but streams won't, and then I get the message "to play video, you need to install the required video codecs". On telegram web and tweetdeck I also get this message while trying to play some video.

Since it's a snap, nothing I do on my system will solve the problem, I cannot install any codecs.

It's firefox 89.0

Firefox crashes and can't use the existing profile when relaunching

Over the past week I've had this error popup a few times when Firefox is launched:

"You've launched an older version of Firefox. Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox."

I haven't yet spotted a pattern, but the most recent time it happened, I had the browser already open and either opened a new window or clicked Firefox in my start menu. The new window showed my homepage (blank tab) but was unresponsive: I couldn't type into the address bar, click a bookmark, or even close the window. The existing window was fine, so I closed that but had to kill Firefox in Task Manager.

When I relaunched Firefox, I got the above error message. Luckily I use Sync, so my many bookmarks are backed up. But of course all cookies have been deleted, so I have to login to websites again.

Firefox is up-to-date (84.0.1, 64-bit) and running on Windows 10 Enterprise. I even uninstalled, cleared out the data in AppData\Roaming\Mozilla (plus Local and LocalLow), and reinstalled.

As I said, this has happened a few times over the last week (3 or 4?) and is starting to get annoying now!

Any ideas? Thanks!

I was playing a browser based game and it popped up with the error saying:

an error occured running the unity content on this page. See your Javascript console for more info. The error was: InvalidStateError. A mutation operation was attempted on a database that did not allow mutations.

uh... what? I have no idea what Unity is or does. I have no idea (even looking here), how to open Javascript console, and I simply loaded the page. How did a mutation operation, whatever that is, occur?

Anyone have any idea what that means or how to fix it? If so, I'd appreciate any help.

Hello! On a certain adult website, all the videos play verrrry slooooly. YouTube videos play fine. And this certain site works fine when I try it with Chrome. I recently added a bunch of adblockers like Ghostery and Adblocker plus and Badger and Decentraleyes and HTPPS Everywhere. Is the problem with one of these? What can I do to get the videos to play at full speed?

Thanks in advance!

Why is Firefox 78 writing to disk constantly? Even when the browser is idle, the hard drive light on my computer blinks non-stop, and I can hear the constant noise coming from the hard drive. The problem is with the browser because the Processor Explorer (available from Microsoft) shows Firefox as doing the constant disk activity, and hard drive stops making noise when the browser is closed.

Hi all,

I've been having problems with firefox lagging constantly. General browsing around feels laggy - and opening new tabs pretty much causes my computer to freeze for a few seconds. During this time firefox causes the CPU to spike to 100% usage.

I've been using firefox for years on this computer with no issues. Hardware is pretty good (i7 5820k, 64GB of ram and an SSD).

So far I have tried:

  • Running in safe mode
  • Using a different profile
  • Downgrading to an older firefox
  • Changing allowed CPU cores from 8, to 4
  • Updated graphic card drivers to latest version

None of these work, and I'm getting a bit tired of the constant slow downs. Chrome works flawlessly, as does all my other software...

Any ideas?

Thanks!

Hi everyone,

Thanks a lot for taking time reading this! :)

I have the following problem with my firefox on Kubuntu 20.04 on my laptop: since a couple of weeks, firefox opens normaly after rebooting, remembered all tabs and my firefox account etc., but it's just not loading anything. I can still type in a web adress or something in the search, I can also still select the drop-down menu on the right ("Open menu") and select e.g. "Settings", but nothing happens afterwords. Same problem for all websites. Some of the main buttons are also not functional (refresh, back/forward). I attached a screenshot from the "empty" firefox (but not sure if that's of any help anyways ;) ).

I tested a couple of things so far, nothing helped:

1) Internet is working, I tested ping, apt is working as well as a differnt browser I installed now).

2) I reinstalled firefox completely by running the following commands:

      sudo apt update
      sudo apt purge firefox // sudo apt --purge autoremove firefox
      sudo rm -rf .mozilla
      reboot
      sudo apt update
      sudo apt install firefox
      (Since I removed the profile folder, the standard tab and bookmarks open/show after starting firefox now, as expeced. I'm also not longer logged in.)

3) By starting firefox via the console, no error messages were shown

4) I created a second ubuntu unser profile, to test if firefox would work there: it doesn't

5) Since I have a dualboot with Win10/Kubuntu 20.04, I started Windows and tested firefox there: it is working as usual.

6) I also obviously tried to google this problem, but either I put the wrong keywords in or this problem is pretty unique/new?

If you need any further information on my system, I'm happy to provide them! Thanks a lot for any recommendations and further ideas, what to do! I'm pretty much desperate for a solution by now, as during home office a not well working system is a pain! ;)

Thanks and stay safe, Katrin

Hello, everyone. My Firefox (v76.0.1, Windows 10 Pro 1909) can't access the English Wikipedia (en.wikipedia.org) and some other sites I need to work with. This started happening suddenly Tuesday night.

This is the error (in English, since my Firefox is in Brazilian Portuguese):

Secure Connection Failed

An error occurred during a connection to en.wikipedia.org. PR_END_OF_FILE_ERROR

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem.

upload.wikimedia.org gives me the same error. The bizarre thing is that Wikipedias in other languages seem to work normally. Other browsers work fine.

Searching it online, it doesn't seem to be a common problem, and it just started happening by itself. I don't remember installing anything on this PC that day. My only antivirus is Windows Defender. I don't use any VPNs.

Tried all solutions I could find on Google. So far I did:

  • Ctrl + F5
  • Edited the hosts file
  • Deleted cert8.db
  • Changed network proxy settings to No proxy and Automatically detect proxy configuration (was in Use system settings)
  • Toggled DNS over HTTPS
  • Went in about:config and toggled network.dns.disableIPv6
  • Started Firefox in Safe Mode
  • Backed up the profile folder and just let Firefox create a new one
  • Rebooted my router

None of that worked.

I work with site builder platforms and since yesterday the error is starting to creep up in those servers, too.

Any ideas? I just noticed that Wikipedia search is gone from the list of opensearch engines also… This is getting increasingly bizarre…

So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

So I've noticed how some video files are able to be played back in Firefox. Some are not able to what so ever, for example I've created a text video using this FFPMEG command: ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 testsrc.mp4

which created the following file: https://astolfo.nl/i/z2ada.mp4 Both the uploaded version and the local .mp4 are unable to be played back in Firefox. However opening them up in edge chromium both files play back perfectly. Besides Edge I've also confirmed it plays back nicely in MPV.

I've tried Hardware acceleration, but both having it on and off did not change the fact that these files wouldn't want to playback in Firefox. Safe mode also did not effect this issue.

Firefox is really nice browser which I am using for more than a decade on my Ubuntu machine. But on Windows machine its battery performance is very poor as compared to Chrome. Firefox almost swallows the whole battery in 1/3rd of the time as compared to Chrome. It is very much consistent on Windows machine. I tried usual tricks of uninstall/install, disabling of add-ons etc. It doesn't seem to be my environment issue. Facing this issue since last year when I resumed using Windows. This is preventing from using Firefox on Windows and eventually on all platforms. Appreciate any help/hints. Thanks!
