this extension adds information to homebrewersassociation.org recipes:

• adds percentages of the malts
• adds gram/liter ratio for hops addition
• ensure SI units are shown
• removes imperial units
• adds a radio button to show the original recipe (useful for debug)

I've only tested it on firefox, it usually works but recipes on the homebrewersassociation website don't have a consistent schema so it can be tricky to get everything right 100% of the time

I've only focused on all-grain beer recipes, this is intended for personal use
