Major A/V sync problem on Youtube
Hi. I'm experiencing a severe lag between Audio & Video on Youtube (video lags audio by more than a second)
This ONLY happens on YT, ONLY on one PC (we have 3) and ONLY using Firefox. I've been through as much of YT as I can find, but nothing changes.
Running FF in safe mode eliminates the problem. I've checked all addons/extensions etc in normal mode, but none are enabled & can't find anything else which makes any difference.
Using Chrome/Edge/IE Explorer all are fine, using a different streaming service (UK TV Play/BBC iPlayer etc), all work fine with FF.
As a last resort, I deleted FF and all associated files, folders, registry entries and caches. Upon re-installing FF the problem returns.
I've tried running without antivirus protection, in case a firewall or somthing was messing with it, bit to no avail.
I'm totally flummoxed, so if anyone can shed some light, it'd be much appreciated. I really don't want to change to another browser as FF has served us well for years.............. but....y'know.
Thanks. Annie

You can try to disable hardware acceleration in Firefox.
- Settings -> General -> Performance
remove checkmark: [ ] "Use recommended performance settings"
remove checkmark: [ ] "Use hardware acceleration when available" - https://support.mozilla.org/en-US/kb/performance-settings
Close and restart Firefox after modifying the setting to apply changes.
You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

You can disable hardware acceleration just for video by going to about:config and changing media.hardware-video-decoding.enabled to false then restarting the browser.
Thank you for the replies.
Hardware acceleration was the issue. I did try that before, but in thinking back, I don't think I restarted Firefox, so just switched it back on.... Idiot!!
All seems ok now.
thanks again.
