Description

When using uBlock Origin on the web player site from Spotify for a while to get rid of ads, eventually playback breaks completely.

For example, when trying to play the first song in an album, it instantly starts hopping to the next song, and does so for a few more songs (in my test case right now, 8).

In some cases, it tries starting playback, then just cancels, but without looping through the album.

Either way, no music is played at all.

This can be temporarily fixed by deleting all data for *.spotify.com, upon logging back in to the web player, maybe one song will play, but then it's back to the behavior above.

Other extensions used

1.) Old Reddit Redirect
2.) Remove DNT (DoNotTrack) header from requests
3.) Return YouTube Dislike
4.) Search by Image
5.) Tampermonkey

Screenshot(s)

There is really nothing to show, as in no error pops up, so I decided to open the network request logger instead, as well as uBlock Origin's logger.

The Firefox network log is from when one song initially plays fine, then when trying to play the next song, it started looping through tracks until stopping eventually.

The uBO logger screenshot is from when Spotify was actively looping through the tracks.

Configuration

System:

OS: ArchLinux
Kernel: 6.8.1
Firefox: 124.0.1
uBlock Origin: 1.56.1rc5

No recent package changes could have caused this.

Can you test in a new Firefox profile with only uBO and its default settings?
