Desperately need a Enable/Disable button
Especially in the beta version, oftentimes there are undesirable behaviors or bugs and going to all the way to chrome://extensions/?id=xxxxx to disable it is not just annoying but sometimes it does not solve the problem. I have encountered a situation where the disabled extension enabled itself again in other tabs (could be a chrome bug). In short, adding an enable/disable option inside the menu is very useful and handy.

@wadawada, https://github.com/gorhill/uBlock/releases/download/1.56.0/uBlock0_1.56.0.firefox.signed.xpi provides this, for reference and precedent. However, it'd be more comprehensive to ask for a way to quickly enable and disable extensions at https://issuetracker.google.com/issues/new and https://bugzilla.mozilla.org/enter_bug.cgi#h=dupes%7CFirefox.
Its extremely difficult bordering on impossible to disable extension on already loaded tab due to the way loaded extension modifies the page. The best we could do is have a button that makes subsequent Tabs load with extension not active.
We can make the active features list appear appear on the front screen.
