 Firefox, it behaves like the Tor Browser build. I run NVDA for screen
 reader on Windows 7.

 Great, then let's dig deeper. One guess I have is that the problem is
 multi-process (e10s)/sandboxing related. Could you disable e10s by
 flipping `browser.tabs.remote.autostart` to `false` in your `about:config`
 and restart both Tor Browser and the Firefox I gave you? Does that change
 things?

 (And no worries about not being well-versed in terminology. :) Just ask if
 I speak too jargon-y)
