Explain when multiprocess mode in Tor Browser gets disabled
Multiprocess mode (e10s) in Tor Browser is disabled under various conditions which could be surprising to users. While we follow Mozilla here it might not be obvious to Tor Browser users what this entails. We might want to think about an FAQ entry or some other blurb explaining when e10s gets disabled and when not.
This might not be something for the Tor Browser manual, though.
