When I try to view a video on YouTube.com, the website takes longer than usual to load (and sometimes causes Firefox to become unresponsive. Embedded videos on other sites (such as reddit.com) are immune to this problem somehow. On top of that, I found that the issue is only present when I am logged into my Google account.

Here are a few quick recordings I made:

https://gfycat.com/GloriousBriefCusimanse (Logged-in on YouTube.com) https://gfycat.com/NiftyRealisticBug (Logged-out on YouTube.com) https://gfycat.com/HandsomeSelfishGerenuk (random embedded video)

I've tried all of the basic refreshing, reinstalling, safe mode, etc., but nothing has worked (other than using another browser or being logged out of my Google account).

Ever since I upgraded to Windows 10, I've been experiencing choppy video in Firefox. In particular, Youtube videos are frequently choppy when viewed fullscreen (but not otherwise, oddly enough), and Netflix is consistently choppy either way. Both seem to be fine in other browsers: Netflix, for example, is perfectly smooth in both Edge and Chrome.

Hi!

In Firefox 38 and later (also tried 43) I examine a really high CPU usage while playing Youtube videos in HTML5 mode. A simple 360p video takes 30-34% CPU in v43, and 56-65% in fullscreen mode.

Firefox 34 works much better here: it consumes 18-25% in both general and fullscreen modes. And even less (just about 8-17% when the video buffering is complete). Firefox 29 works a little worse, but still much better than the new versions.

I have Windows 7 x86 and an nvidia graphics card, so https://support.mozilla.org/en-US/questions/1077259 should not apply especially since older versions work just fine. I should also note that I am using a fairly weak PC for testing this (2GB ram, old Athlon II CPU), yet again older versions never caused any troubles.


I also noticed that in v43 videos from Youtube don't keep buffering until 100% anymore. While completing buffering reduces CPU usage in 34 much, it doesn't seem to have this effect in 38.

Hello to all, I have a Windows 10 computer and 64-bit Nvidia graphics card GTX 970, with operating system, drivers and firefox all updated. No plugins and add-ons. I have a problem with flash player video with Firefox (no problem with other browsers) classical screen "is a crash occurred in the Adobe Flash plugin" appears.

Several forum say try to remove hardware acceleration. In Firefox options I tried to uncheck the hardware acceleration, but then when I check on Flash Player window settings, hardware acceleration check box is always enabled and if I click to remove the tick is not selectable.

I also tried it in about: config setting true: gfx.direct2d.disabled layers.acceleration.disabled and then re-initialize the plugins database, reinstalling Flash, but the hardware acceleration check box is always enabled, no chance 'to deselect.

Important: If I uninstall Flash, the video works.

There 's a way to use flash?

Thank you.

Hi,

Both flash videos and Html5 videos don't work. Html5 freeze on the first frame while flash videos crash the flash player. If i restart my computer i can watch videos for a short time. I have tried a bunch of fixes but nothing has worked.

I originally thought this was a flash problem but i don't if it is. My post on Flash support: https://forums.adobe.com/message/8723717#8723717

I am also going to put a post up on windows support in case this stems from a deeper problem. If you have any advice on isolating where this problem is occurring that would be great, just so I can ask the right people.

I'm getting really desperate for help

Thanks in advance, Michael

Firefox 46.0.1 is very slow loading pages. YouTube videos also take a while to load then keep buffering. Twitter won't log-in until I click log-in button a number of times. Some web sites seem OK but most struggle. I have Refreshed Firefox and also started in Safe Mode. My internet is fast. I have updated graphics driver. I considered going back to Firefox 45 and decided to download it. Firefox told me it would take 3 hours and I let it download for half hour. Then I downloaded it in Internet Explorer and it took one minute. My OS is Windows 10 64-bit. This slowness seems common judging by community posts. If this can't be fixed I will have to go through the hassle of installing version 45.

2K and 4K video won't play if codec is AVC/MP4

Hi.

When i try to play videos on Youtube or Vimeo, they won't play if they are 2K (1440p) or 4K (2160p), AND the codec used is AVC/MP4.

The video will play fine on resolutions up to and including 1080p. Selecting a higher resolution, or viewing fullscreen and having it auto-select 2K or 4K, and the video immediately stops playing and never resumes. Selecting 1080p again will continue the video playback.

If the codec is WebM/VP9 however, it plays just fine even at 2K or 4K. For Youtube I can see this is the case by checking the 'stats for nerds' info. For Vimeo this is a guess* but it shows the problem is broader than just Youtube.

For instance, this video won't play at the 2K-setting: https://vimeo.com/163590531

https://www.youtube.com/html5 shows me 7 blue boxes with checkmarks. So everything is supported.

These settings are all enabled in config:

media.mediasource.mp4.enabled;true

media.mediasource.webm.enabled;true

media.mediasource.enabled;true

.*Disabling mediasource.mp4 removes resolutions above 1080p from the available options. Disabling hardware acceleration in the browser does not fix the problem. I'm using the latest Firefox, and recent Nvidia drivers. 150 Mbit connection.


I would like to be able to view the 2K and 4K AVC/MP4 videos. Especially on Youtube where new videos appear in this format. If the video becomes popular Youtube will replace it with a WebM/VP9 version, but this can take days, if it happens at all. Meanwhile I'm stuck at 1080p, and having to manually downgrade the setting before I can watch, because Youtube auto-selects 1440p for my machine (2560 x 1600 display). And I want to watch it at 1440p.

What can I do to remedy this that I haven't tried already?

Thanks.

Edit 1: Just tried watching the vimeo video linked above in a VM with Windows 10 and Edge, and it plays just fine at 2K there. I also tried a Windows 7 VM with Firefox, and it won't play at 2K. And I tried a Windows XP VM with an old IE, and even that plays at 2K.

This strengthens my belief it is somehow a Firefox issue.

Edit 2: OK. Now I'm confused. I tried Win 10 + Firefox = works. Win 10 + Chrome = works. Win 7 + Chrome = works. Win 7 + Firefox = doesn't work! Win 7 + Firefox and all add-ons disabled = also doesn't work. All this in VM.

So Win 10 + Firefox in VM works at 2K. Other browsers in Win 10, and Win 7 work at 2K. But Win 7 + Firefox doesn't work at 2K in VM and on my host machine. The VM probably excludes my graphics drivers as the cause.

Is the problem a combination of Windows 7 + Firefox??

YouTube HTML5 videos fail after 23 minutes 18 seconds. The audio becomes croaky and intermittent and the video freezes. I have to click somewhere on the video timeline for video & audio to resume. The video quality doesn't appear to be a factor because videos at 240p, 480p and 720p fail at the same time (23 mins 18 secs).

I disabled all add-ons and still had the problem.

I did a fresh install of Firefox and—before installing any add-ons—tested YouTube videos and got the same issue.

I've experimented with the "Override automatic cache management" box being unticked then ticked (with cache limit set to 200MB, then 400MB).

I don't experience this YouTube playback problem with Google Chrome (using Windows XP).

Im building a new webpage with video background. The problem is that Firefox is the only browser that have problem with html5 autoplaying. If page was loaded atleast one time the video is working correclty, starts right after the page load automatically but.. if page is loaded for the first time in most cases the video in background doesn't start and show something like TV's snow.

Facts: - I don't think its code issue, atleast not 'video' tag (tried many configurations thinking it might ), - I'm also sure its not problem with video - tried few videos, - tried all formats - it happens with all of them: mp4, wemb, ogg, All at the same time and individually, - it's not problem with my PC - been trying on windows, mac and linux, - Its not plugin - i don't use any with FF.

Check it out here: http://strona5.nanit.webd.pl Just do it in private session and close window after every load so you'll see that its lottery.

Regards.

We are unable to watch any YouTube videos with Firefox. I've added and removed Flash plugins, added and removed HTML5 (several different plugins for it), deleted all history and cookies, started in safe mode, uninstalled and reinstalled, and basically did every other troubleshooting issue I could (aside from DNS because we use corporate DNS). We are unable to show training videos and other work related videos in a corporate environment. We either get the message 'an error has occurred' or 'no video with supported format and MIME type found'. When you first load up YouTube, the featured video at the top of the page comes up as 'secure connection failed'. You can't load the site at all without https, so that wasn't an option to try. Our Flash is updated to the most recent version, so there shouldn't be a security issue there. YouTube is allowed through our firewall. Any help would be appreciated.

Since this latest update to 48.0.2, I have lost the ability to view videos on YouTube, Fox News and other news sites. YouTube gives me a snowy screen indicating "Your browser does not currently recognize any of the video formats available". Fox News gives me a black screen indicating I need a plugin, but does let me know the identity of the plugin. Searching the Add-ons site with a word search, I get so many choices, but non address what I need. Have installed the YouTube flash player and YouTube High Definition. Still unable to play the videos. When looking in the Add-ons/Plugins section and click on the link to check and see if my plugins are up to date, the "Keep your Firefox healthy..." page, indicates no plugins were found. I am running Window 10 Pro x64, with the Anniversary update, keeping up with Windows update. Do not want to have to use Edge or IE.
