OK, I didn't think anything really valuable was there, so I just deleted
~/.mozilla/ entirely. uBlock Origin loaded fine after that.

The bad news is that after I again added the only other add-on that I
use, Vim Vixen, uBlock Origin did the same thing again, dying on startup.
So it's obviously due to a bad interaction with Vim Vixen.

I don't know who to blame for this. Vim Vixen itself is working fine.
I guess there are other people using uBlock Origin with different
add-ons, and if no one else complains about uBlock Origin failing,
then the problem is with Vim Vixen, or perhaps with Firefox.

I can't stand to be without either add-on. So in the meantime I will
continue with the workaround of disabling and then reenabling uBlock
Origin whenever I start Firefox.
