Description from extension meta

Because injections are for sick people.

Description from store Comcast started injecting Javascript into some users webpages – this extension blocks it as soon as its injected, as per my comment on https://gist.github.com/ryankearney/4146814#comment-810151

  • (2017-03-30, v:1.1.1) Would love a greasemonkey script
    Any chances of a greasemonkey script for those of us not using Chrome? It would be greatly appreciated <3
  • (2016-08-30, v:1.1.1) Trader Jc: 3 years and no update?
    Annoying popups are back, but only for a millisecond. (It must be my other 10 popup blockers doing the work. LoL.) This is a millisecond too long. Can you update your extension to work properly. Down with Comcast. Btw, thanks.
