I imagine the extension works fine, but the thing is, my chromebook cant work with this extension. and i cant find why that is. i don't know if my chromebook is a specific make and model, or if my chromebook isn't completely updated. But the video attached to this says that the extension's compatible with chromebooks, even though it's not working for me. \_(-_-)_/
It doesn't seem to work for Chrome OS. I downloaded the zip file but what I got seems to be for windows and they don't have an available file for chromebooks, or at least as far as I can see. Also, the steps are way too vague and don't really help if you don't already know what you're doing. I think it should be made clear it doesn't work for chromebooks.
It works for me (and in the Brave Browser no less)! Just install the extension, download the zip file it tells you to download, extract in contents into a local folder (I used "Documents/Open in FireFox" as my folder), and then double click on the install.bat file. Hit any key in CMD Prompt when it opens and you are set! Well probably anyway.
