Really helpful and a must-have extension in my eyes - I use it all the time and can't imagine using a browser without it now.

This extension is necessary to using any browser. It has saved me hundreds of times in the past year.

Sollte endlich mal Standard von Firefox sein. Ich empfehle den Kontexteintrag für den Tab standardmäßig zu aktivieren, dafür das symbol in der Taskbar nicht standardmä´ßig zu aktivieren. (pin to adressbar by default: no) Da man das symbol selber eigentlich nicht braucht, wir brauchen nicht endlos viele Knöpfe, ein Rechtsklick reicht ;)

Hi, unfortunately the addon seems installed but doesn't show anywhere on my Firefox ... I would like to understand why it doesn't and how to fix that ...?
I don't know how to contact the creator of this addon anywhere else than here unfortunately.

HELP ???

Edit : Thanks for the answer, it works perfectly now.
