Rated 5 out of 5 stars

Thanks for adding app button like firefox, only one suggestion that it opens/flairs horizontaly while arrow shows downward can you give us option to flair menus downward or horizontaly and accordingly arrow should be placed. also though very nice and prompt work can you replicate firefox style app menu?

Very Nice! Rated 5 out of 5 stars

One of the missing / or not working property of thunderbird now set right. Only if any App button like firefox would suit the best along with this extension.
