I am happy to see that there are people who value privacy =)
However, be careful messing around with the about:config, you might
eventually do more damage than good ;)
I usually suggest TorBrowser for when you want to be private. And add to that
common sense, since a global adversary will hardly be defeated by Tor alone.
I will have to check those on my browser (I am running Debian). Actually,
just wait a second...
I am checking them now, and number 1 is set to true. I would suggest that
someone who wants to keep it true, to at least change the
dom.storage.default_quota to a minimum. Mine has it at 5120, how much is
yours?
number 2 doesn't really matters to me, so i will jump that one.
number 3... oh the old prefetch dillema. Always considered the "preloading"
of anything to be a very delicate issue. How much is it worthy to gain in X
and lose in Y? Anyway I have to say that mine had this set to true. So, I
guess I will disable it and test it for a few days.
THANKS!
Again, when you want privacy, use TorBrowser. So far, is the best thing we
have.
