Works 25% of the time. Most of the time it somehow turns into Always on Bottom, i.e. it makes other programs stay on top instead of your browser. Some other times it make other windows of your browser stay on top instead of the window you wanna be on top.

I can't be bothered anymore.

WARNING!!
This extension will not run without first downloading a linked app. Malwarebytes identifies the app as a machine-learning type of malware.

This sentence "Starting from Firefox 57 it requires additional application" is everywhere, but nowhere does it say what the additional application is. What application is needed?

It is working very well for me today! thanks!

Требуется установка дополнительного программного обеспечения, без него расширение не работает - об этом в описании ни слова.

Works about half the time. Sometimes it just prevents firefox from being on top at all.

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.

The download contains malware.

I've uninstalled and reinstalled both the add-on and aot.exe too many times to count and yet it still doesn't work. I've read reviews with similar problems with the only proposed solution being to check if it installed properly, but how could it install improperly in the first place? As of now I'm deleting the add-on itself and its external program until a solution presents itself to me.
