Thanks for this kind review.
FYI, the last update dates from almost a year ago, I don't see where the "broken behavior after a recent update" comes from.
I use the addon everyday without any problem as do a few thousands other users. I have recently updated to FF 29 and it works correctly.
As for my email address, I have tested it and it also works correctly. I receive emails on it from AMO users for requests, donations, etc...
