Can't even get it to load. Firefox already installed I don't need 6 more additions.

I can not create a new user script. From popup menu "New user script..." not work!

Update 4.6 version delete all my script! :( There are currently 0 userscript installed!

Самопроизвольно удалились ВСЕ скрипты.
Больнинство самописные. И бэкап не делал, т.к. даже не предполагал, что такое возможно.
Я просто в ярости!

Removed the 3.17 feature of installing User Scripts.Totally upset.

indirmek istemeyiorum ama indirmem lazım

Forgot to post a comment after the whole debacle a few months back.
Stay away from this extension, I moved to TamperMonkey.

The manage user scripts for Popup Mouseover is missing. This is a broken addin missing functionality.

Every script broke.
