Review for RequestPolicy by bucket'o'clues
Rated 5 out of 5 stars
This is a must have along with adBLOCK edge and (beef taco or ghostery) and NOscript and (greasemonkey or scriptish)
Perusing the interweb without any filtering is almost as foolish as using outdated sms texting when zero-cost xmpp texting is available for every device.
Even if you're a facetard you can learn to use RequestPolicy. Wisely tinker to restore essential functionality only
Hopefully the developer or a forker will ad subscription functionality to encourage more widespread usage. I'm confident many of the adblock subscription maintainers would happily release f/oss subscriptions for RequestPolicy -- especially for online finance and webmail should one's contracts with such be at least sensible with respect to the high value of user privacy and not be raping it for profit by default.
