It doesn't play very nice with Vertical tabs, most presets are obv broken and making one from scratch is a real chore without previews.

Still does exactly what was on the tin at release though. No notes with conventional tabs. It's just a real shame.

edit: they fixed the saved themes tab issue!
Decent extension with pretty thorough customization but the saved themes tab is covered by the menu preview and I can only access it with uBlock's element zapper. Additionally, the background images are never displayed as they're shown in the preview and the 1mb limit is a bit difficult to work with. A zoom-to-fit or resize option for backgrounds would be appreciated. Would be a 5 stars if not for those QOL issues.

Extremely nice.

Confusing just at a first glance, but I didn't read any instructions yet.
IMPORTANT and helpful. I have had an unfixable problem with the icons for my addons showing up. Somehow, this addon fixed it! So I'm thrilled that I added it. Even after disabling and restoring my original theme, the problem stayed fixed. It would be really helpful if a developer could check on what this addon changed to fix that problem. I will check my about:config setting it to show only changed values.
I will be using this addon as soon as I have time to read all of the documentation.

Installed hoping it would enable changing color of parts of my chosen theme like text or icons, but whatever change you set, just overwrites the theme you chose with the ones from the extension. What's even worst is that the "revert all" button completely removes the theme, while the chosen one still shows as "enabled", so you have to first disable it enad then enable it again.

thanks firefox
we really liked this thing

Would love to use it more but why there is a ridiculous 5MB limit on locally saved themes. Is this a bug? limit on saved themes on local storage? Makes no sense..... deleting themes to free up space doesn't free up space. Themes disappear spontaneously. Export and no import of themes. Installing imported themes not possible - Firefox reports file as being corrupt. Still a much needed simple extension all things considered, please fix it.
