Ever since the end of February Firefox has had a habit of crashing on me at random, usually just a tab or so but there's been times where the whole browser just ups and crashes. I am using Firefox 73.0.1 (64-bit) on a Windows 7 Professional computer.

1. This mainly occurs when viewing a video (mostly Youtube), scrolling down on pages, or opening or switching to a new tab.

2. Beforehand if there were issues it would take a few seconds to load the tab, now it just instantly crashes.

3. I've tried uninstalling and re-installing, clearing everything, turning off add-ons, and changing options and nothing has worked. At best, I've stopped it from crashing on launch and disabling add-ons.

4. This issue does not happen on other browsers, nor has my computer shown any unusual behavior.

5. It did not start immediately with the new update, which I got the 20th. It started occurring a week or so after.

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

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.

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!

My MacBook Pro is running OS 11.0.1 and using Firefox 83.0. My battery runs down faster than it used to. Apple suggested checking the Activity monitor and I noticed several instances of FirefoxCP Web Content. I have lots of tabs open. Most of them are using <1% of CPU, but one is about 50%. Is there any way to figure out what that is other than shutting down the tabs one at a time and watching the Activity Monitor?

Recently I have noticed that where there are drop down lists on websites I visit the drop down function no longer works properly if I am using the Firefox browser. If I click on the arrow in a drop down list box the list briefly appears then disappears almost immediately making impossible to select an option from that list. I don't have this problem if I use any other browser like Safari and the drop down list function used to work on Firefox, so presumably this is a bug unless there is something in preferences that needs changing. I am using v88.0.1 on mac OS Sierra 10.12.6. Any help wud be appreciated

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

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,

Trying my luck here as a last resort. I cannot read videos on FF (I end up with the following message "This video file cannot be played.(Error Code: 102630)") except Youtube ones.

I read few articles and already tried the following: make sure I have the latest version of FF, uncheck "Use hardware acceleration when available", install FFMPEG, install K-Lite (and restart FF each time).

Nothing worked so far so any other tips from the community would be great.

I'm using Windows 10 and have a couple of add-ons only (LastPass and uBlock origin).

Thanks a lot in advance,

Max

"If you are connected but behind a firewall, check that Firefox has permission to access the Web."

I get the above instruction when I can't access a website--but I don't know exactly what I'm supposed to to. My firewall is the one installed with win10.

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?

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?
