This addon does work, I know that it seems sketchy that you need to download a file to make it work but bear with me.

First install the addon and click the thumbnail icon (or the shortcut ctrl+shift+f7) download the extra file. Unpack it and copy the files to your firefox addon folder.

To find your firefox addon folder go to about:support in your firefox browser and there should be an area called profile folder, click the button next to it labelled "open folder". Now copy the install, uninstall and aot files into that folder.

Now run the install file and your good to go. If you press the thumbnail icon (or shortcut keys) the firefox window will stay on top. Press the key again to stop the firefox window from being on top.

This addon is great, it only got 4 stars because of the extra digging I had to do to get it to work (I'm a windows user by the way). If you could find a way to fully automate the process this addon would be a perfect 5.

Installed this addon, used ctrl+shift+F7 shortcut and all i got was window telling me to download that addon from github repository, and link to some packed archive with exe file. Not suspicious at all.

not work

it does work, just unpack the rar file, and copy the new files to the firefox folder
C:\Program Files\Mozilla Firefox

....bs not working.

does not work. This app does nathing, just tells you to download aditional file, witch is virus! Need to be reported imediatly and removed from firefox adons!

No funciona

Works good for when I'm programming stuff based on factorio, but it doesn't work with fullscreen applications. (e.g. Looking at a walkthrough for a game)

add the addon.
press ctrl+shift+F7.
unpack and install the repository from the link provided in the new tab
now use same shortcuts

!!!

This still works on quantum, however after installation, they ask you to run a .bat file to make it work. So far works perfectly fine, no suspicious behavior. Recommended!

This add-on is not available on your platform.

it's great and missing on iMac

Not working properly. The addon page says the bugs with Firefox 60 are fixed, but they are not. Either that, or it's incompatible with Windows 10.

Used to work properly a few months back, on my Windows 7 PC. Hopefully it will be fixed soon.

works perfectly, after I hit the bat File, the button can work.
只需要点击.bat文件就可以了,按钮变成可用状态

Didn't work. I went to the github link stated in the instructions and downloaded the file. After I hit the bat file and the aot app, nothing happened, this lead me to uninstall the extension and the download that it required.

das war eine tolle Erweiterung . leider funktioniert sie seit 57 nicht mehr.
wiesooooooooooooooooooooooooooooooooooooooooooooooooooooo?
gibt es eine alternative surfen und gleichzeitig film sehen? Ubuntu?
