Comment (by Rastislav Kiss):

 Hmm, this seems very interesting. I have tried few screenreaders, turning
 them on after Tor browser's start, and there seem to be different reaction
 for everyone.
 Jaws, 64-bit screenreader, murders Torbrowser regardless of the current
 position in system immediately after startup.
 NVDA, 32-bit one, Torbrowser keeps running while I'm not in its window.
 After focusing it, even this can be survived if i left it before NVDA
 starts to load the page, what is announced by voice, then Torbrowser
 crashes.
 Microsoft Narrator, Windows built-in screenreader, totally surprisingly,
 this works! The page loads, can be read and there are no crashes. Although
 navigation by arrow keys doesn't work, it doesn't in Chrome as well, so
 this is rather Narrator's bug than Tor browser's problem I guess.
