Playback restarts a few times randomly (FF)

[itsfarseen]

Firefox version: 87.0
OS: Arch Linux

I have been facing this problem for quite a while. Like an year or so.
I haven't been able to reliably reproduce the problem. It happens quite frequently and randomly.

Symptoms:
The buffer suddenly becomes empty, even if the buffer was fully loaded a moment ago.
Then playback starts buffering.
Then sometimes playback continues, sometimes playback restarts from beginning.
And sometimes, instead of restarting, playback resumes with video.

Other extensions installed:

If other people who are having this problem share any info they have, we could try to find what's common in all of these configurations.

Same here. Furthermore, playing frequently stops when the player jumps to the next video/song and seems stuck (displays loading animation + red play button on the center) and doesn't play unless I actually press play or reload the page.
Already tested turning off shields, uBlock, VPN and violentmonkey but the only thing that seems to resolve it is turning youtube-audio off.

Firefox 88.0b5 (64-bit) Windows 10

The extension shows some errors so let me know if I can be of any help trying to solve this:

Edit: Like @itsfarseen I also have the extensions stylus and sponsorblock installed (will try disabling those)

Same here, I'm getting red play button sometimes and the confirmation dialog "Continue watching?". I'm using ublock origin too. And the two things I mentioned didn't happen before install youtube-audio

[itsfarseen]

@zubus does it happen after like 15 minutes later or does it happen during the first minute of the playback?
Youtube actually has this "Continue watching?" prompt, that will come up after a while even when we are not using the extension. Probably to save their bandwidth.

@itsfarseen after like 15 minutes as you said, but this did not happend before to me

[itsfarseen]

I see. It happens to me regularly, even without the extension.

With audio mode disabled, It does not happen for me.
With audio mode it does happen on longer content.
Latest firefox, with youtube premium (so I dont have those "Still Watching?") pupups.

@itsfarseen
Each title in my playlist restarts at the end of the title and is played twice,
then playing passes over to the next item in the playlist.
It does not loop all the time.
