First attempt to play a video plays instantly, but clicking any video I've viewed since a cache clear or if I refresh the page, the videos load shifted to the right (no sidebar video list). After a second, the sidebar loads in pushing the video to the 'normal' position, and as soon as this happens the video--that has played around 1 second--fails.

I have disabled all addons, refreshed firefox, disabled HW accel. Starting Firefox in safemode completely breaks it and I can't even navigate to a page, let alone test YouTube. I've reinstalled only 2 of the addons I had before since they're clearly not the issue.

Win10 1803, Firefox Quantum 61, Nvidia GTX 1080ti (driver WHQL 398.36)

hello, i have a Raspberry Pi 4 with 4GB and Raspberry Pi OS installed. (2020-05-27-raspios-buster-armhf.zip)

when i use the stock Firefox ESR (installed via sudo apt install firefox-esr) and watch videos (e.g. on Youtube, Vimeo, ...), Firefox does crash some times. according about:crashes, i already have submitted about 60 crash reports.

but watching the reports one thing is missing. when i open firefox from the console i can see some output, that is not appearing in the reports.

... firefox-esr: /build/firefox-esr-RgOFaD/firefox-esr-68.11.0esr/media/libcubeb/src/cubeb_alsa.c:1255: alsa_stream_get_position: Assertion `delay >= 0' failed. ExceptionHandler::GenerateDump cloned child 3366 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Failed to open curl lib from binary, use libcurl.so instead Firefox ESR crashes when playing videos on Raspberry Pi OS (Debian)

during watching videos in firefox there is more different output to see that seems to be harmless. but always and only this line is printed to console, just befor Firefox crashes: firefox-esr: /build/firefox-esr-RgOFaD/firefox-esr-68.11.0esr/media/libcubeb/src/cubeb_alsa.c:1255: alsa_stream_get_position: Assertion `delay >= 0' failed. so i assume this is the main reason, why Firefox crashes on my system.

any idea how i can get these issue fixed? at the moment when i want to watch videos reliable i am be forces to use the external VLC Player by copy the url to VLC - at least for Youtube videos. but i want to watch videos from other web pages as well and i prefer to watch videos in firefox directly.

If I force quit the browser and then reload it I can play about 5-6 videos but after that it just buffers and tells me to restart my computer. I have removed adobe flash player and reinstalled it. I have removed the ad blocker I had on the computer and didn't re-install it. I have tried other things that are on the internet, nothing works. Any suggestions... please

When I've been playing YouTube videos lately, I've noticed that a bunch of black boxes have been appearing over the player interface (The controls below the video) while the video is playing. Unfortunately, I can't provide a good screenshot, as the boxes come and go too quickly for me to get them. This issue still occurs if I restart Firefox in safe mode. I think it started happening with Firefox 37.

The mp4 clip shows a bar at the bottom and on the right there's a symbol that looks like a speaker with a bar through it. There seems no way to change this. The mp4 clip will play perfectly in WMP and from the website on a Samsung phone.

I've recently built a desktop PC with this configuration:

Ryzen 7 1800X

Geforce GTX 750 Ti (driver version: 399.07)

16GB DDR4 RAM

250GB SSD + a HDD for data only, no system files

Windows 10 64bit

External Sound card Scarlett 2i4 1st gen. [it worked fine with my old Windows7 desktop]


Any audio (soundcloud, zophar.net/music) or video (youtube, twitch, facebook) stream has the same problem: it randomly skips frames. I mean that video nor audio are interrupted, they continue, but they skip some "frames".

This bug occurs with the current official version, the current beta version and the current Nightly.

This bug does not occur on my laptop, windows 8 running an i5 CPU and no dedicated GPU.

This bug does not occur on other apps. I've tried: VLC, Facebook app, Twitch app, Microsoft Edge, Internet Explorer, Winamp.

Yes hello, as the title says some videos go slow after i pause em to look on something else, specifically in a site called animeplus.tv i watch the videos there, then i pause em for a bit to check for something else, or another video in another site or well whichever reason, the thing is when i return to this video and resume playing it, it gets very slow playback, the audio is fine, but the video itself is not working properly, so far i just seen this issue happen in that website but perhaps is the flash player? i dunno i removed a addon that i though could be the issue but is not. and when i try this on Google Chrome, it works fine, i pause the video check for other stuff, and the video still plays like normal. so i am hoping for some ideas in what to do cause i do like Firefox and i do not want to transfer over to another browser.

In Firefox video frames don't scale properly. This affects both HTML5 videos e.g. youtube.com and Flash videos e.g. twitch.tv. When switching to Cinema view in youtube, or closing the side panels in twitch, the frame will extend to the left and right, leaving black bars at the side, but the video does not scale and the frame does not increase in height. I don't have the issue in Safe Mode and also not in Chrome. However I still have the issue in Firefox with all extensions disabled. I tried to delete cookies, cache and refresh Firefox, but the issue still exists. I also tried to disable Hardware acceleration in both the Flash Player and Firefox, but that also does not solve the issue.

I am running Windows 7 64 bit and Firefox is my browser. All of a sudden I can not play videos at places like Democracy Now and many other web sites (E.G. Malcolm Gladwell) but most of Youtube is okay - except sometimes. I thought this may have been due adGuard but disengaging it or starting FF clean with no ad ons has no effect.

I was just informed by Costco Concierge Services that the reason is that both FireFox and Google Chrome have decided to “no longer support” certain add ons or plug ins (what is the difference if any between these tech terms of art?) and therefore if I can not play a video I will have to use Internet Explorer. Discovering what videos I can or can not use is a hit an miss case by case basis.

So, first is this true? I can not imagine Firefox or Google Chrome making a change that would actually require its users of many years to bump their prime product and, instead, turn to its prime competitors. That seems like suicidal sabotage. We are just every day end-users and not software engineers and the explanations I find are absolutely incomprehensible technobabble.

In plain English what is the real problem? What is the fix? And has Firefox actually decided to make us dump Firefox and turn to its competitor just to watch certain videos? Has Democracy Now decided to continue using a video format that is no longer supported by FF?

The attached pic is just and example. DN uses jW player but I find this problem at other web sites too.

I have developed a very basic opening page for my web site. It contains a 45 second movie. It works on IE, Chrome, and Safari but will not work on Firefox. Why?

I have spent numerous hours attempting to try workarounds with no luck. I am considering just putting a statement on my front page that says I cannot make this site work properly with Firefox.

It would seem to be in Firefox's best interest to figure this out and fix it vs being the lone browser out there where basic common video formats do not work well.

Please let me know if there is a very quick workaround to make this work because I am certainly not going to spend any more time trying to figure it out.

Thanks for listening
