Excelent!

Great extension! Rated 5 out of 5 stars

It exceeded my expectations!

Thank you, Justin, for their valuable contribution.

Mozilla Firefox does not have the option to hide the orange button. And that button occupied a considerable space. Too bad the same.

Justin, I love the hint of "Alt". I did not know.

Now, I use my two excellent extensions for Firefox:
App Button and Remove Yahoo! Mail Watcher. The latter I use more than two years.

Mozilla Firefox and its employees are to be congratulated!

Thank you, Justin!
