Error with two simultaneous accounts #20
Description
Following up on our IRC conversation. I'm running the add-on on two accounts: one regular and one incognito. I'm often logged in on both at the same time. It works fine on the latter, incognito account, but when I open it on the regular one it seems to get stuck on importing messages. I've run it for about an hour and I still get the loading screen. This account also has very few PMs so it doesn't seem like it should take that long.
