I agree there is a gray area here in filtering versus protection. I
don't have a concrete answer at this point. A fine question is, Where
is the boundary between protecting the user from an anonymity
vulnerability versus open access to information (for good or bad)?
Torbutton protects against known issues within Firefox, but are ad
networks external to those issues or is it something we need to mitigate
for the user (unsuspecting or otherwise)?
I may sound like a broken record here, but I don't use an ad blocker
plugin. RequestPolicy does just fine to block 99% of the ads because
99% of the sites on the Internet use a 3rd party ad network that isn't
in their full domain. (I don't actually know if 99% of the sites on the
Internet use a 3rd party ad service, but roughly 99% of the sites I
browse for information appear to do so.) This also breaks content
delivery networks and turns most sites into text only, but that's fine
Clearly I need to do more testing and use more features ofprivoxy to see
what it can do.
