It works well, but I don't understand why I can't generate a "mask" email using it? Seeing as this is one of the features of having a paid account, the fact I still have to go to the website to generate one is quite jarring and annoying. But otherwise, this addon works very well, thank you.

Does what I need. About the only thing that could be better is dismissing the help text when I click the toolbar button.

You throw out terms that don't seem to have clear meanings. You tell me to "create" something, but I don't know what it is -- much less what one looks like. It's really horrible to pay to subscribe to something that doesn't give clear instructions, understandable examples, purpose, etc.
