I use firefox 83.0 on Ubuntu 20.04. Browser does not play videos on Twitter, Reddit or Netflix. Youtube plays some videos but some videos show error "your browser does not currently recognize any of the video formats available". I cannot find any viable solution. what should I do?

I installed chrome and it plays all the videos. So there must not be any problem in OS.

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, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?

Hi everyone,

it's been 2 days now since every time I open Netflix and Amazon Prime videos won't play. A yellow bar saying: "The WidevineCdm plugin has crashed" keeps coming up!

I'm using Firefox and I'm on a MacbookPro.

I've tried everything: restarting/shutting down device; reinstalling Firefox; deleting widevine folder and activate it from the adds on page; tried on other browsers (works on safari but not on chrome); contacted Apple / Netflix / Amazon / Google nobody was able to help; I also ran these websites with my Mac in safe mode...nothing was able to resolve it.

What can I do to fix it please?

This started to happen out of the blue...I haven't installed anything! It was working fine until the day before...

Hello, I have trouble getting sound playback on firefox (checked 85.0 and 78.7.0esr both 64 bit) on windows 10. I checked sound on youtube, and netflix. I checked other applications like spotify and mpv, and soundplayback there is fine. Also it works on Firefox nightly (87.0a1).

What i have already tried: - restarting my computer - opening windows volume mixer and see if firefox is muted - updating my audio driver - different playback devices (Device over HDMI and Line out) - reinstalling firefox - uninstalling firefox, delete folders in C:\Users\$username\AppData\Local C:\Users\$username\AppData\Roaming - new install with fresh downloaded installer - restart to safe mode

Since firefox nightly is working i suspect that maybe the application name "Firefox" is muted somewhere. This could explain why i can reproduce my error on ESR and stable but not on nightly.

Thank you for your help in advance

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!

Yesterday I got a new Mac, running macOS Big Sur (11.1). Previously I was using Mojave (10.14.6). Now on Firefox a lot of pages fail to load -- they show a blank page. Among them:

https://web.whatsapp.com/ https://open.spotify.com/ https://www.nytimes.com/puzzles/spelling-bee Citibank (after the login)

Some of these pages do open in a Private window. However, I already cleared all my cookies and cache contents, and I still cannot load thes pages in a normal window.

Can you suggest what I need to do? Thanks!

ADD: When trying to login at https://profile.theguardian.com/signin, at first I got an error message saying to "make sure that Javascript is enabled". But now it just goes through, except that the site doesn't know that I logged in. And again, in a private window I am able to log in.

It looks like I should just do all my work in a private window now, which seems strange

Hello Everyone

I'm having troubles with playing some Youtube-Videos and Twitter Videos. I had to re-install my Windows 10 (64 Bit) due to some hardware-issues which are not related, and I'm having this issue since then. Here are the steps that I already did:

-Removing all Add-Ons -Starting in Safe mode - Deinstalling and reinstalling Firefox, then starting in safe Mode -Deinstalling Firefox with a tool that also deletes all Firefox-Related Registry Keys and App-Data Files and reinstalling it to a different path (other HD) -Disabling add-ons - Disabling Open264 Videocodec and widevine content decryption module (more just because of frustration^^, but I was then able to play some Youtube videos after this one) - mediasource.enabled is active (and all the other ones as well) -Installed addons (even though it didn't work with them disabled as well): NOscript( youtube videos are allowed, some of the are working), Ublock Origin, Video Download Helper, HTTPS Everyhwere, Tree Style Tab, Limit distracting sites - Updating to the newest Firefox-Version (which came out today)

Btw: on https://www.youtube.com/html5/ it tells me that everything works fine and I have of course the newest Firefox-Version installed.

Do you guys may have any other ideas?

Thank you for your help.

Kind regards,


Gabe
