After I updated tampermonkey to 5.0, it's eating my CPU and leaking memory. Had to rollback to 4.19 (Firefox 120.0.1 64-bit)

About Your question. No, I haven't!

After update to 5.0.0 at 102ESR, with RuAdLIst JS Fixes, Yandex maps gave up loading map images. Had to rollback to 4.19.0.

Latest update causes FF to consume 30-90% CPU and eating more and more RAM, that caused lags and in the end full unresponsive.

P.S. No enabled "Never remember history" or "permanent private browsing".

Latest update causes FF to consume more and more ram until it becomes unresponsive and eventually crashes.

stopped working as of 12-12-23 after updating the extension

Не уверен, но похоже расширение майнит во время простоя именно в firefox, в chrome такого поведения не наблюдается. Благо есть Violentmonkey.

I am using this to enable a script that runs on Firefox at YouTube playlists to enable a download of the playlist items' details. It has worked flawlessly and I am well pleased.
