Not useful. I've been trying for years to get rid of the useless Firefox scrollbar, which I never use, because it is too thin to try and click on it. I thought this add-on would allow me to finally do so. However, as clearly stated by the add-on when you try to change the scrollbar width, this is not allowed by Firefox. You can only change the scrollbar colors, but I don't know why anyone would want to do this

Does what it's supposed to do well. I love it

muy bueno

It's easy to use and very useful add

This extension is good, change the visual of websites, but don't run in every site (Yt for exemple)

memudahkan

why does this add-on need, only (permission) it ask for " Download files and read and modify the browser’s download history"

does not work for firefox. the only option that worked - is customizing colors. and that is irrelevant, I can do it by myself w/o any extension.
