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, I'm using Firefox 85.0.2(64-bit) Windows 10

While I'm testing local testing for website, whenever I typed/entered localhost OR localhost:8000 Firefox keep redirecting/guesing subdomain for it(which="www"). Made my testing messed up.

There's same issue on https://support.mozilla.org/en-US/questions/1216065 None of those work.

set: browser.fixup.alternate.enabled to false or Connection Settings with No proxy

Please, stop. Chrome and Edge behave normally. This site need darkmode :/

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!

Following a Windows 10 update, I tried to open Firefox and the following popup message appeared. "the code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." I have tried several times to download the latest version of Firefox, but during it's installation the same error message appears. How can I fix this problem and get Firefox to work normally.

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

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?

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?

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!

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.

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.

Since a sudden power outage, when I use firefox maximized (not f11) there's a white border around 3 of the 4 edges - not including the top. It's about 2mm thick, and only goes away if I press f11.

I've tried uninstalling, cleaning out all the old files and reinstalling firefox; I've tried disabling and re-enabling add-ons; I've tried changing my screen resolution to something else and switching back. All to no effect.

This has never happened before, and my monitor is at 100% resolution. Can anyone suggest what else I could try?
