I have been using this add-on for years now and it works flawlessly. The devs listen to the feedback and implement them as well.

Version 1.0.4 works great!

Being Asked to enter the email and password over and over is just nonsense. The problem is that with every login attempt, the extension reloads all the opened Firefox tabs!!!

efficace

Being forced to input login details over and over again, really frustrating - Firefox not set to delete cookies on restart.

great
