After much consideration, this app is officially a 1 star. I'm no computer expert, and the fact that his app used to be my favorite. But after Firefox upgrade, this app stop working! again, i usually just download stuff, click it and voila! i would search google for a fix and do this, and do that but i have no clue what they talking about! Common Mr. Developer sir. Make it simple and work for id**t users like me!

works like a charm, has a little helper exe

he podido usarlo una sola vez. Lo desactivé en el gestor de complementos y al voloverlo a activar nunca más funcionó. El problema es que al hacer click en el icono de la chincheta me abre una pestaña y me lleva al link https://vm-devr.github.io/aot/ y está instalado y activado, tengo capturas de pantalla por si hace falta más info (no se como colocarlas aquí).

He desinstalado el complemento, firefox, reiniciado, vuelto a instalar firefox, el complemento y sigue igual. Por favor ayuda.

The extension works perfectly! Very awesome extension.

unique and very useful extension

Works just fine. It's hardly the dev's fault that the latest Firefox requires an external tool, but this extension works and it's not difficult to install.

Works as intended, thank you!

Pre-quantum, this was one of my favourite extensions. Bringing in something Mozilla themselves forgot. Now, though, with the requirement to install a separate app from a random developer, just seems fishy. I certainly can't use it at work anymore. A real shame. I'm blaming Mozilla for this one, the whole extensions change is basically just "here's Chrome but with the name Firefox", which is crap. Sorry for the negative review, I just can't use this anymore, and I'm a little mythed, as I did like this extension.

Ich finde das Add-On super, genau das was ich brauche funktioniert auch so weit so gut mit allen programmen. Ich habe nur ein Problem mit einem Spiel bei dem dies nicht funktioniert, dabei wird das Spiel trotz des Add-Ons mir im Vordergrund angezeigt bzw kann ich nur zwischen ihnen switchen. Ich würde mich freuen wenn Sie mir weiter helfen könnten. :)
Schonmal Danke im Vorraus :D

Ctrl-Shift+F7 just brings up the add-ons tab. Clicking on the github link brings up the files but running them doesn't change anything. Doesn't work at all.

Thanks, it works exactly as expected.
The Ctrl+Shift+F7 shortcut is very usefull for windows without a direct access to the extensions button (answers Audrey's questions below)

Gott sei Dank funktioniert dieses Addon wieder. Ideal zum Video gucken. Bedauerlich, das Firefox selbst diese Möglichkeit nicht bietet.

Very liked extension until recent changes. If you require additional app for your extension to work you need to publish sources - you already using github to distribute it! But without sources it looks like malware or just incompetence to me.
edit:
Ok, i found solution for me. I'm using previous version of FF, so i can install corresponding version of extension. But still this situation with binaries and no sources is suspicious

It works awesome thx!

Works as advertised, fixed 'broken' Firefox 57

I see 3 files but where is the file uninstaller ?

Thank you very much for this extension. I only have one problem: when I pop out a window (a video, for example), the top bar is reduced and I don't have access to the pin button. Is there a way to add it in a menu, so it is accessible in this kind of window?

EDIT: sorry, I didn't find how to answer your comment, so I try to edit mine and hope you will see it. The pop out is an option I have on some video player, such as Picarto. I have the option shown on this picture: http://puu.sh/yyy48/5fdd061b5a.png
When clicking on "Pop out", I have this kind of window: http://puu.sh/yyy6i/f668f7de2d.jpg
There is only a limited number of option and, sadly, the pin is not among them. I hope there is a way to make it appear.
