Excelent! Rated 5 out of 5 stars
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!
