Browser / Version: Firefox 133.0
Operating System: Linux
Tested Another Browser: Yes Other

Problem type: Something else
Description: Firefox hangs at or towards the end of the video
Steps to Reproduce:
The video playback works fine but at the end (or when I hit the close "X") the entire browser hangs. Audio playback continues normally, and the terminal shows

[GFX1-]: Detect DeviceReset DeviceResetReason::FORCED_RESET DeviceResetDetectPlace::WR_SIMULATE in Parent process
[GFX1-]: Detect DeviceReset DeviceResetReason::FORCED_RESET DeviceResetDetectPlace::WR_SIMULATE in Parent process
[GFX1-]: Detect DeviceReset DeviceResetReason::FORCED_RESET DeviceResetDetectPlace::WR_SIMULATE in Parent process
[GFX1-]: Detect DeviceReset DeviceResetReason::FORCED_RESET DeviceResetDetectPlace::WR_SIMULATE in Parent process
[GFX1-]: Detect DeviceReset DeviceResetReason::FORCED_RESET DeviceResetDetectPlace::WR_SIMULATE in Parent process
[GFX1-]: Detect DeviceReset DeviceResetReason::FORCED_RESET DeviceResetDetectPlace::WR_SIMULATE in Parent process

I first started seeing this in 132.0b6 or so and it remains in the current 133.0b5 . With the current version a process called "RDD Process" now keeps burning CPU but when I SIGKILL it it becomes a zombie process. It disappears fortunately when I kill the browser by sending a SIGINT to the main process. One of the 2 kill signals causes an extra terminal output line:

[GFX1-]: VideoBridgeParent receives IPC close with reason=AbnormalShutdown

I cannot reproduce this in a private window nor in a stock FF profile so this appears to be caused by an extension.

Still shouldn't hang the browser this way though, IMHO, which is why I'm filing the issue.
