Easy to use and I really needed this to organize my searches and favorites

This addon doesn't work in Firefox 54.0.
It installs, and is visible in addons, but there's nothing to give the option to use it. No toolbars, or buttons, or even options.
When selecting bookmarks on the menu, the basic Firefox bookmarks page is shown. Still no option to use the bookmarks addon.
I've given it one star, but will update to five stars if it's fixed.

Not working on android

Not even a sort option.
Install it if you want but you're getting less than you already have.

so easy

Good addon. And in future updates will appear in the search folders?

I found it best in my experience of other browser,s extensions.
Ok.

todo bueno FF es mi favorito

It just freezes firefox android.Had to uninstall it to make firefox work again.

No compatible with Android version

Ok

This extension does work as description said. But, it noticeable slow when loading its view. In my system it actually need 2 seconds to load top tree. More if I open the main tree.
Probably because I have 2000+ bookmarks and multi layers folders.
