After having upgraded my distribution from Rosa R8 to Rosa R9, some functionality in google plus got broken just from having tampermonkey installed. The searchbar, app selector, notification and account pop-ups stopped working and posts could't be expanded or commented leaving only the links on the navigation bar the only thing working, This makes the site unusable.

One thing to note is that this behaviour is not present after a fresh system boot but after reloading the page this starts happening and nothing except a reboot will do anything to stop this with the extension enabled.
