Most of the negative reviews that I've read are completely wrong. This extension does what it says on the package. Simple and easy to use. Hence the 5 stars.

Ich liebe dieses Add-On und möchte es nicht mehr missen! Es funktioniert ohne Probleme und man kann (so wie ich) sogar die PWA-Web-App Fenster anheften. Danke vielmals an den Entwickler! 5 Sterne! <3

pretty good add

простая, но такая удобная штучка

Easy to install and works right away!

It is working very well for me today! thanks!

I can't make my browser ALWAYS ON TOP since a firefox update.

awesome.. its suppose to be the standard feature of browser

I registered an account in Firefox only to write it, I want to say that addon works fine!
I did not find any problems! Originally afraid that it could be a virus, I read the reviews and decided to download it, and now I use it for almost a year.
