Diễn đàn hỗ trợ Firefox

So basically it has been 2 days since this happened, before update 88; main page of youtube doens't load correctly (only few thumbnails) and only after refreshing it for many times; other browsers load it fine; I did everything I could find and think of, including re-installing clean install, and even restoring windows to a week ago. any ideas or help are appreciated.

I have a new business website http://affordable-tutors.com/about-our-tutors and I tried to put in my video https://youtu.be/EQxd_cowXPg

but it gives me the following error. Website will not allow Firefox to display the page if another site has embedded it

What can I do?

Yes, I own all the rights for that video.

The issue is when the youtube video is being viewed (only happens on youtube), it suddenly freezes with a healthy grey bar and a connection, while the audio continuously plays on. After the freeze or stutter, the video never gets out of sync with the audio but actually jumps ahead to where tit is. Meaning I'd lose out on 1-3 seconds of visual footage which I have to rewind to watch again. After the rewind the video doesn't get stuck on the same spot but further down it happens again. It sometimes never happens on some videos I watch but the ones that it does happen, If I went back to watch it again (refreshing tab or finishing the video then coming back) It happens again. Usually repeats within 5 minutes of it happening at minimum. Which is very annoying.

At first I thought this could be a issue on my display drivers. I went searching for solutions all over the web. Common reasons I got for this was that my internet might be slow. Which is bit true ig. But I can view up to 1080p videos without buffering or any problems. So Idk how that's the case. Another reason I got was that it might be hardware acceleration, which I turned off before I got the problem again. Another suggested add ons might be the case. So I turned some off and under more advice used a completely new portable app of firefox (no logins, addons or settings changes) and I got the same results. I also reinstalled display drivers. Disabled the hardware acceleration of the new clean app. And still got the issue. The only time I didn't get the issue was when I was using Chrome. Or Edge.

I've cleared cache and all data,history as well. So I'm really stumped. Someone asked me to make a completely new windows local user admin account and try again. And it happened there as well.

Edit : While trying to get evidence of this, I've discovered that sometimes if I rewind twice or go back more than I usually do the stutter tends to usually repeat on the same place. You can see it in the video.

leads to youtube

I've lately noticed that when I watch some YouTube videos I get this white dot on the page for some reason, refreshing the page makes it disappear. What causes this?

I have searched for this problem, and only come across outdated information about Youtube's intentional changes to slowdown Edge and Firefox in 2019. This is not that.

When I load a new youtube video, the video will buffer as normal, and then buffering stops. Then there is a delay of about 10 seconds. You can see from my screenshot that the buffer is filled just fine, and playback begins about 10 seconds later. This also happens if I skip ahead/back or to any position in the video. This firefox install is on a new install of Windows 11, with a new xps 13. The previous xps 13 with windows 11 didn't have this problem, and I don't have this problem on my desktop setup with windows 10.

I use a few addons: decentraleyes, ublock, duckduckgo and I have privacy protections set to strict. I have tried a few troubleshooting steps and the problem persists. Things I have tried:

• safe-mode
• fresh install
• installed additional codecs
• used user-agent workarounds to show as a chromium based browser
• turned off hardware acceleration

The problem doesn't happen on chrome, but it does happen on Edge, which is strange. Because of this, I'm wondering if there is something going on with codecs. In the firefox screenshot posted, the codec used is vp09, same with Edge. But in Chrome the codec is av01.

Lately I refreshed Firefox so I can boost it's performance cause it was running just a little bit slower than usual. Since than YouTube does not remember my selected resolution. Every time I close the tab, in the new tab it will have a much worse resolution and I did not have a problem until now. I am a system administrator and I'm currently learning programming as well, so I tried a lot of things to try to overcome this problem. The only extensions I have is Bitwarden, uBlock Origin, Cookie AutoDelete. And yes, youtube.com and *.google.com IS added to cookie AutoDelete. But even without it it's not working.

I have provided the Troubleshooting Information from about:support: Click Here for Troubleshooting Info

I also know that there are extensions like YouTube HD or Enhancer for YouTube what would solve this problem, but I would like to keep my extensions as minimal as possible.

Thank you!
