Rogue extension's XPI (including install.rdf)
A rogue extension called "Firefox Access Plugin" (id: firstname.lastname@example.org) is causing random ad popups in Firefox and should be blocklisted. From a quick look through the XPI (attached), it seems that this extension's only purpose is to pop up advertisements.
Blocked in production: https://addons.mozilla.org/en-US/firefox/blocked/i43
Out of curiosity, where was this reported to us?
I got this from a user on SUMO who reported random popups in Firefox.
