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

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?

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?

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, 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…

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

After updating to firefox 72 (maybe it was after 72.0.1 - I did not have time to check so fast) videos on youtube started stuttering. When I start video everything seems fine but after a while it starts microstuttering - image is twitching, movement of camera is not fluent.

It looks like it is related to all videos on youtube. I watch mostly 1080p 60fps and these most often cause this issue. Example video: https://youtu.be/1La4QzGeaaQ It is easy to observe it at 1:27 with camera movement and terrain being fluent or not. If I pause video and resume play after few minutes it seems fine for minute but then it starts being choppy again. It does not seem to be related to video quality. I had 0 dropped frames in yt stats. I found workaround - if I set media.wmf.vp9.enabled to false and restart browser with this setting set to false everything is fine. But when I set it to true (like it always was for me) problem starts to occur. However no matter what I set youtube still shows "codecs: vp09". I do not have this problem on microsoft edge. I never had this problem on firefox 71 and I did not add any new extensions since few weeks. It must be new firefox fault, not my hardware or configuration.

I open it in safe mode and I see the address and search bar and everything but I am unable to click on them and honestly it doesn't even look right when I open it up in safe. I provided pictures. I have been all over the settings and looked into multiple forums that all say the same things and tells you how to get out of fullscreen mode but not anything on how to stop it from happening automatically on open. I have uninstalled and re-installed as well.

Anyone have any insight?

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.

Sometime recently (as of 11/3/19) Firefox ceased to reliably print entire web pages. Instead it prints the first, last, and sometimes one middle page. The print preview function suffers the same error. Since the problem shows up in print preview I don't believe that it is related to the configuration of a specific printer. It doesn't seem to be a coding error in the web page as other browsers like IE, Chrome, and Opera render the page accurately. Because I don't print pages often, I can't tell with what version the problem showed up.
