My fixes above are only relevant to New Identity. Do you make use of
https://gitweb.torproject.org/torbrowser.git/blob/maint-2.2:/src/current-
patches/firefox/0004-Add-a-string-based-cacheKey.patch in JonDos? If so,
test your per-tab isolation or whatever uses it with images.
https://encrypted.google.com/images/srpr/logo3w.png seems like a fine
image to source from two tabs. If it actually loads in both tabs, it's not
cached. Tools->Web Developer->Web Console should be sufficient. I am still
looking for an official machine to hold random tests like this. :/
