Excellent, lightweight plus customizable and easy to use. Keep up the good work. thanks

It's the easiest way to make your own Firefox theme. Unfortunately, exported themes are always corrupted, so you can't share them easily.

i really like this add-on however after updating firefox, this add-on is no longer working. please fix this

Decent styling utility. Unfortunately, it doesn't work as expected with vertical tabs. The background image/pattern option doesn't apply to it as it would with horizontal tabs.

Very nice! easy to customize :) so cute :)

Exported themes cannot be used in Firefox. Attempting to import them produces an error message.

Export function outdated, won't work for Addons Marketplace

The .xpi file still uses manifest v2, which is no longer accepted. This causes errors like “incomplete theme”. Mozilla hasn't updated this export feature even though v3 has been required for a while.
