Firefox Support Forum

initially it buffers for a second...suddenly message appears 'error occured..'...only youtube is having this problem..other website videos buffers fine..i have tried all the solutions you have given in the these pages...but its not working..please help me out...

Youtube works weird now: when video is played and I try to open commentaries branches, the page reloads (so the video starts playing from the beginning), and this happens only the first time (I can write and read commentaries after these reloadings) for every video I see. I tried deleting all my plugins, but this wouldn't work. What should I do?

when i go to youtube and don't scroll down everthings find but if do there a 60% chance that it will stop responding and crash. and i have uninstalled and refreshed firefox and no changes am getting to the point of leaving firefox if i can't fix it

When watching videos on YouTube or listening to music on Spotify Web Player, SiriusXM web, Pandora, etc. switching the default audio device in Windows does nothing, sound continues playing through the originally selected device.

I am using Windows 8.1, Firefox version 37.0.1. I have tried downloading the beta Firefox, problem was not fixed and it make some of my extensions unusable.

Whenever playing YT after a while Firefoxs starts becoming choppy or suddenly there is no sound any longer. Than the video stops and nothing works unless I restart my laptop.

I built my PC about two months ago, until now everything worked fine. Two days ago I installed a graphics tablet and still everything worked fine. But today, as I got to youtube, the mouse freezes, and it won't let me move my mouse, until I leave youtube. But if i use my tablet I can control youtube like everytime. So I tried deinstalling all tablet drivers, rebooting, but it still doesn't work. Please help, I don't really want to control youtube by a graphics tablet all the time. Btw I am using Windows 10.

Video on Youtube is so slow when it start to play on Firefox. It seems like Firefox process or convert video on Youtube. Firefox take about 5-10 seconds and then Youtbe video is played smoothly unlike the previous version of Firefox that video is not played but both of those 2 issue are bad at the same level

1 minute i was downloading the next i wasn't able to i don't know why i didn't change anything checked space and the add on and tried different addons but nothing happened when i went to download

I have the latest version of Firefox, have tried clean install. Tried removing all plugins and extensions. Other sites do have significant memory usage but nothing like yahoo. Feel it is probably a shockwave issue with the site.

I installed Firefox after the new update, and some YouTube videos (usually longer ones) won't load and show the error message in the title. I have Windows 10 N, but I installed the Media Feature Pack, and Flash is also installed and up to date. I have no trouble loading videos in Chrome, so it seems to be a Firefox thing.

Thanks in advance.

Je ne comprends pas ce qui c'est passer depuis quelques jours j'ai fait une mise à jour de mon Firefox, qui est devenu Quantum et depuis, j'ai eu pleins de problèmes, entre autre le téléchargement de vidéos sur YouTube est devenu impossible pourtant avant cette mise à jour tout m'était possible bien évidement avec les extensions exemple j'avais une extension qui me donnez un bouton rouge ENREGISTRER, et l'enregistrement démarrer alors que maintenant je vois bien le téléchargement en cours, puis après quelque minutes plus rien ? je pense que cette version de mise à jour n'est pas au point.

Last night when I was trying to go on Youtube it show the first two frames of the video and stop all of the sudden. I tried restarting my computer, uninstalling and reinstalling Firefox, safe refreshing Firefox, and this morning its still acting up. Here's a picture of what it does, please help me

Whenever I open a YouTube video, the moment the page has finished loading, Firefox instantly scrolls the page down about a centimeter, hiding a small portion of the video behind YouTube's search/menu column. To resolve this, you have to scroll up everytime you watch a video, which is a major annoyance. I have experienced this thoughout many macOS and Firefox releases, tested it with and without add-ins – it doesn't matter, it always happens.

Is this issue known, and is there a known way to fix it? Otherwise this would be an amazing fix for upcoming releases.

Firefox 62 on macOS 10.13.6

I used google chrome and found that using youtube was fantastic. But coming back I find youtube in firefox short on quality when watching youtube on firefox.. why,is the quality that goes as high as 720p where as youtube has a quality as high 2040 and higher and in 4k

I've updated Firefox and now some of the pages have got graphical glitch occurring in random moments. As for gmail I can't specify how to reproduce it, but on youtube it goes like this: 1. go to the random video 2. move the mouse cursor around (over the video and then over the title) 3. at one point the black background will show up under the videos in the right column or under the video timer

I've tried with and without acceleration with the same result (as attached).
