Последняя версия съедает всю память и нагружает процессор на 100%. Раньше такого не было, а теперь браузером с этим расширением просто невозможно пользоваться.

Not open-source but pretend to be(GitHub code never updates)

can confirm that memory leaks (eats all free memory - up to 50gb ram for 3h), high cpu usage on v.5.
Also pages do not open in new tabs the first time
"Modify existing content security policy"=off, "Never remember history"=off, private=off

Breaks my user-css-style for twitter. Rolled back to 4.19.0 before witnessing more unwanted issues.
Took me a while before realizing tampermonkey 5.00 was the culprit. Yeah, a while :/

edit 2:
Beta 5.0.6191 had the same issue. (but totally breaks youtube's feed page no matter what)

Settings I ventured in then, and found out that -Modify existing content security policy (CSP) headers = no- instead of -Modify existing content security policy (CSP) headers = yes- fixed my issue 👍

Update broke the scripts im using for tumblr

I also have memory leak (v5.0) and crashes. I not use "Never remember history" or "permanent private browsing". Plz fix it

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.
