 Replying to [comment:3 cypherpunks]:
 > Ok, found a way to replicate the issue, if you set {{{pdfjs.disabled}}}
 to {{{true}}} and repeat the steps in the OP you get it to crash. (Not
 however that I didn't modify this pref when I first encountered this
 problem, it was a standard install of the Tor Browser and for some reason
 pdfjs didn't work as I explained in #comment2)
 > Haven't tested on 7.0.1 but it may likely be affected as well.

 Yeah, I just found out the same: Going to `about:preferences#applications`
 and setting the pdf option to "Always ask" AND being in e10s mode
 reproduces the issue for me.

 Now, not sure what disabled your pdf viewer, though. The standard install
 comes with it enabled and we did not change that over the years.
