Firekeeper – How did I miss this one

I can't remember where I saw this yesterday, it may have been on Internet Storm Center. Anywho, there is a Firefox add-on/extension/thingy called Firekeeper. From their webpage at Firekeeper - detect and block malicious sites.

Firekeeper is an Intrusion Detection and Prevention System for Firefox. It is able to detect, block and warn the user about malicious sites. Firekeeper uses flexible rules similar to Snort ones to describe browser based attack attempts. Rules can also be used to effectively filter different kinds of unwanted content.
Features of Firekeeper include:

  • Ability to scan HTTP(S) request URL, response headers and body, and to cancel processing of suspicious requests
  • Encrypted and compressed responses are scanned after decryption/decompression
  • Privacy friendly - no data is send to external servers, all scanning is done on the local computer
  • Very fast pattern matching algorithm (taken directly from Snort).
  • Interactive, verbose alerts that give an ability to choose a response to detected attack attempt.
  • A detailed view of suspicious response headers and body
  • Event logging
  • Ability to use any number of files with rules and to automatically load files from remote location.

I have played around with it a bit and it is quite nifty.

Caveat: It breaks twitterfox. I will be posting a bug report about that.
