Not consistent.

Super cool

no transparent background

And still no option to color that hideous/hard to see gray scroll-bar :(

the saved themes button is hidden under the browser popup, which makes it very unusable when trying to go into themes you made previously even if i use this once but its annoying when trying to do multiple use

When adding custom background, it leaks from below the toolbar/bookmark toolbar. Is annoying when a webpage is a contrasting color...please fix?

This is a an easy to use tool for nearly complete customisation and it's well worth it. The only thing that could've made this better is a larger file size limit for background pictures (so i could toss literally anything on it lol). Windows Paint is enough to make a fun background to add to the colors though, and the files are small enough that I haven't had any trouble.

Amazing, would love to have the ability to have a dark new tab page similar to the classic firefox dark theme

Great add on and I hope the developers continue to add options. One problem I have is that I can share my theme but I see no way to import/use the theme I share.
