Hi Jacob,
I've played with this for ~10 minutes, and it didn't do anything bad to me
:)
I've browsed a few "known" websites, and a few "unknown", with and without
rules; it looks fast (which is good) and didn't crash or hang anything
(which is even better).
Is there any specific tests you'd like
Uhm, actually, as soon as I hit "send" I went on Facebook (which I didn't
check earlier).
All the background content (scripts/CSS) did not load. Upon refreshing, it
did (and the page loaded fine).
I closed and reopened Iceweasel: same thing happened again.
Let me know if you'd like me to test so
