Recipe Filter per HallOfSame

This is a port of an existing Chrome extension, just changed to work in firefox & FF for Android.
It searches web pages for certain div markers usually used in recipes and displays that as a pop up to skip over the usual pages of story & filler on recipe sites.
Original chrome extension here: https://chrome.google.com/webstore/detail/recipe-filter/ahlcdjbkdaegmljnnncfnhiioiadakae?hl=en
There is a version of this extension on the Mozilla site but it no longer works with Firefox and doesn't support FF for Android.
