Summary

  • Objective: Detect extensions on Chrome and Firefox

  • Authors: koto, bcoles, nbblrr

  • Browsers: Chrome < 18, Firefox < 50

  • Code

Internal Working

Loops over hardcoded extension IDs in Chrome and Firefox to detect which ones are installed.

Feedback

  • Apparently it has been blocked recently by Chrome : it is not working on my Chrome 22 with error : Denying load of chrome-extension://bhmmomiinigofkjcapegjjndpbikblnp/manifest.json. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension. This has been corrected through whitelisting since Chrome 19 (see here)
  • Firefox hack still works on Firefox 17.
