Firefox Support Forum

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!

Really too much PR_END_OF_FILE_ERROR

https://www.bbc.co.uk/news/uk does NOT have issues.

this error message occurs regularly ( and sometimes with amazon.de)

Please fix the bug that causes this, or allow a option to ignore the (non existent) error.

I have 4 tabs open, and my computer is running and running... come to find out, FF is running 17 tasks in the background... why? And what can I do?

Thanks!

my specs Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz 2.21 GHz 16.0 GB (15.9 GB usable)

I cannot access my bank on my computer. I have access to everything else. When I input my credentials all it does is continuously load. What seems to be the issue? I can access my banking through a different browser but not Firefox.

Hi everyone I have a question I have used Firefox as my default browser for many years. This mourning I started getting “Secure Connection Failed An error occurred during a connection to www.youtube.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_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.” When I tried to go to any site other than the homepage. I find it very suspicious I can only use Bing to get on the web. Anyone know what is going on.

I am locked out (padlock icon with red slash) of all the websites (except gmail) that I use all the time. I did a “refresh Firefox” but that did not help. What could have caused this all of a sudden? HELP!

been at it a week everywhere. how can I change the resresh rate about 60MH. desktop preferences is greyed out. command line didnt do it. not a programmers, please keep it simple. was hoping a GUI would make life easier. its blocky on a slow screen scroll. tried loads everywhere. I think it might not happen in chrome.

Whenever I click on this link, https://www.onlineviolintutor.com/lessons-1-10-resources, I get the below error message.

"Secure Connection Failed An error occurred during a connection to www.onlineviolintutor.com. Peer received a valid certificate, but access was denied. Error code: SSL_ERROR_ACCESS_DENIED_ALERT"

I tried on several different browsers and always get the same error message. I'm trying to access this website link so I can download one page of sheet music.

Can you help me figure out what's going wrong?

Thanks, Sheila

This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

I cannot use mozilla as it keeps asking for my primary password and the one I have does not work. I have also lost a lot of my info in my tabs at top to link to accts. When I click the upper right under my email it says account discontinued????????

I have tried to reinstall a number of times and I'm exhausted. I'm not good at this (aging Boomer Grandma) Sometimes security goes way too far. Tired. Can you fix this?

Firefox randomly freezes when i try and open a website or do anything then will load forever. Can not open a new tab as it will just load forever when i try and open a website. Only fix is to open and close it.

My Firefox browser has been crashing for several weeks. I have been a Firefox user for quite some time now but never experienced anything like this. This happens at least a couple of times a day. I have refreshed the Firefox app on my computer, tried turning off the extensions for a while (I use 2 add blockers), but nothing seems to fix the issue. I'd hate to switch to another browser but this is getting very frustrating.

I'd appreciate any help you could provide.

Firefox taking aproximatly 10 seconds to start loading a link after pressing it, I have reinstalled the browser, reset to factory setting but the system remains even in safe mode. I recently formated the computer that's when the issue started to happen.

EDIT: I've solved it by installing Kaspersky's extension. I have been troubled by an issue that every time I perform a search on some websites, the page will first freeze for ~10s, during which I can't click on anything on the page. However firefox itself is not totally freezed, like I can switch tabs without any issues, but if I click on the icons of extensions (such as my adblocker) it won't give me any response. After the freeze the page started to load normally. I have tried disabling all extensions, reinstalling firefox, updating to beta, and disabling security.tls.enable_0rtt_data, but none of these works. Other browsers on my device work normally, including Edge and Chrome. Websites that freeze during a search: Google, Bing, Musescore, Duckduckgo Websites that DO NOT freeze during a search: Github, Youtube, Twitter I have encountered this issue both on 117.0.1 and 118.0.
