Feature Request - 1 button remote log-out and password wipe

I’d like the ability to log out of all synched devices, and remove passwords from those devices remotely with a single click. The current version is a bit too clunky and slow.

I work on several shared computers at work, some where single windows/linux logins are necessarily shared by multiple users. It would be very convenient to use Firefox account as if it were a windows or linux login, with the option to quickly log out and just wipe everything clean from my details, without using multiple menus/pop-up boxes.

Even better if you could also log out of google and other important places - all in one click.
