Simple, works well, very convenient and helpful, and as advertised. I also appreciate the well-chosen toolbar icon.

And although the description doesn't currently say so, it's open source, available on the creator's github georapbox/firefox-theme-switcher.

Thanks very much for making this!

Divine work bro! I love this thing so much! Thanks!

Better if users can add custom text tags or categories to help sort and choose themes. The ideal behavior is that users can quickly choose a dark theme from themes with a "dark" tag or under the "dark" category without trying to enable each of them.

It works and does the job, we can switch between the installed themes quickly

Works perfectly. I use it to sync with dark theme on fedora Linux

As a web developer this addon saves me a LOT of time going through troublesome menus while testing. Thanks a LOT! It could be one less click if clicking on the theme switcher icon opened the list of themes, instead of having to click the theme switcher icon and then the drop down menu.

Does the job
