Investigate Multiprofile/"Switchy" Support for Tor Browser
On dev-privacy, Sid and Steve suggest that the best way forward to creating a Tor Mode for stock Firefox is the creation of a separate Firefox profile that contains all of the settings and addons we need. Then some form of UI like the Switchy addon could be used to launch new Firefox processes with this new profile. This seems like a good idea to me.
In fact, I'm curious how seamless Switchy is with Tor Browser right now, and if it is safe to use. Power users often request the ability to run multiple Tor Browsers at once, but this is not easy to support right now. I'm curious if Switchy may make things easier for them.
