Firefox freezes when i open a particular youtube video !

已張貼

Hi My firefox freezes when i open this youtube video https://www.youtube.com/watch?v=QAU_8GEgSwI

I cant do anything in the interface which goes glitchy after a while, forcing me to shut it from task bar and restart. It took me a while to understand the problem was with the youtube video. If i dont open that link, everything works normal. Also, Earlier (till yesterday) i was watching that video without any such problem.

I tried updating and reinstalling firefox completely but still facing the same issue with this particular video. I cant figure out whats the problem !

Please help.

I am watching the clip now. So far no problems.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Hi Still having the problem. I completely uninstalled flash player our of windows.

I also tried watching the video in safe mode which delayed the freeze to a few seconds but still have the same problem.

I also installed 'youtube flash player' plugin to firefox but still have the problem.  :/ the UI freezes within 2 seconds when i click the link and the video/page is loading.

When I check "Stats for nerds" on the right-click context menu, it indicates two potential issues (full size screenshot attached):

(1) I'm getting VP9-encoded video. This can be a real CPU hog, but it's common on YouTube these days, so if you don't have CPU issues on lots of videos, this might not be the thing to focus on.

If you think it's still worth ruling out, you could try this extension that pushes YouTube to use H.264 instead:

https://addons.mozilla.org/firefox/addon/h264ify/

(2) YouTube is sending me 60fps video, which I believe is double the data to decode compared with more typical 30fps video. So that may be more than you want.

I am aware of a userscript to hide 60fps capability from YouTube but I haven't tested it since July 2017 so I don't know how well it is working these days: https://greasyfork.org/en/scripts/23329-disable-youtube-60-fps-force-30-fps

This is also a feature listed for Iridium for YouTube, which has a comprehensive feature set that might be more complicated than you need, but could have some goodies you've always wanted: https://addons.mozilla.org/firefox/addon/particle-iridium/

This one lets you select lower resolution for 60fps videos, but I'm not sure that will improve your overall experience?? https://addons.mozilla.org/firefox/addon/youtube-auto-hd-fps/

Hey Thanks for digging in but it seems to be working fine after a complete system reboot; must be a windows glitch, i dont know though.

Also, since the video was working day before yesterday so i cant have any fps/codec problems from youtube.

Thank you for the help Jscher and fred ^^

You could try one or both of the suggestions I gave before and see whether they make any difference.
