Comment (by Wonder):

 1. Steps - I first noticed it was a consistent problem following these
 steps (if this is what you mean): launch, duckduckgo search 'posteo de,'
 open new tab, search 'posteo de mail guardian article' and then freezes
 after about 30 seconds. If I change the order of the steps and stay on Tor
 project homepage and then, say, open same search in new tab, it takes
 longer - up to a couple minutes to freeze.

 It seems as though when I stay on the search result page of duckduckgo or
 tor project homepage for that matter instead of navigating on, it takes
 longer to freeze.

 2. Same issue 1.5 months ago when I first installed the browser on a new
 computer. Could not use tb and left it, came back to it today,
 reinstalled, same problem - tried to troubleshoot which brought me here.
 So it is '''not''' a new problem in that I've not used tb before
 successfully on it.


 3. Has been consistently set at Low (default). Changed to medium, exactly
 same thing & same time span (30 seconds).
 '''Changed to high, has been no crashes so far (30 mins)'''

 4. With the latest alpha 7.0a4, I get exactly the same issue (followed the
 steps above, same time frame freeze) (security setting at default). Same
 with security setting at medium. '''I'm still waiting to see if a crash
 occurs at high but it hasn't happened so far (+5 mins) so my guess is,
 same as stable version, security set as high then no crash occurs.'''
