Tor Browser with High Security is not affected, Win XP is not affected.
Is this the SSP in action?

@gk I can confirm: tested on latest Tor Browser (6.5.1) security settings set to Low with Windows 7 32bits SP1.

This looks okay to us; I guess Mozilla may come up with a differemt fix but we can pick that up later.

Resolution: fixed
Status: needs_reviewclosed

Pushed as commit fd67e2869611a961893a868fa0891cf4ded173eb to tor-browser-45.8.0esr-6.5-2. It seems that esr52 is somehow not affected as I can't get a nightly build to crash. So, I am holding off applying the fix to our upcoming alpha.

Turns out we need it for esr52 as well. I pushed commit c90a0868540a9771cc10bdc1cf91b8f6a8f37603 (on tor-broswser-52.0.2esr-7.0-2).
