Best Dark theme so far Rated 5 out of 5 stars

Its an indispensible addon for those who like light-text-on-dark-bkgd themes like Twilight, Monokai, etc.

Works perfect with windows 10! Rated 5 out of 5 stars

I'm a user of pentadactyl and always looking for a dark theme until this one. I will keep this one as my only choice!

Great Theme, but one problem Rated 5 out of 5 stars

This is my all-time favourite Firefox theme and I am using it since multiple years, but I have encountered a problem:

As of Firefox 53 (beta) the media playback UI is broken.

Enable the theme and play a simply mp3 file via firefox, you will notice that the media playback UI is broken.

It would be nice if this could be fixed :)

The ONLY FireFox theme! Rated 5 out of 5 stars

I`ve been using FT DeepDark for more years than I can remember, perhaps 5 or 6, and it is simply the ONLY theme I will ever need. Deep, dark, clean and cool. I DARE you to try it and not LOVE it. Huge thanks to the dev, Steva, for making my iNet time so much sweeter.

Sharp, clean, compatible - best dark theme for FF on Win Rated 5 out of 5 stars

If you want your Firefox dark and handsome, without a lot of flashiness, this is the theme for you. No background graphics, no shiny gradients, just pleasantly dark with good visibility, just enough customizability, and compatibility with lots of common extensions and settings. (It works great with TabMixPlus, for example.)
The developer keeps it pretty well updated and is responsive to questions and requests.
I cannot recommend FT DeepDark highly enough for every installation of Firefox on Windows.

Flawless on its own and with lots of other extensions Rated 5 out of 5 stars

Simple, clean, comprehensive, and best of all, highly compatible. I use Tab Mix Plus, The Addon Bar, Tile Tabs, Tab Tweaks, etc. - these change the shape, size, behavior, and more of the UI. FT DeepDark handles it all without skipping a beat, unlike several of the most popular and best-rated dark themes out there.

When FF updates, this theme may appear to be 'incompatible', but immediately or shortly after, it can be reinstalled without issue. I'm not sure if this is a bug on FF's part, if the version-matching is too strict, or if there are actual incompatibilities that the developer (Steva) needs to fix, but like I said, the delay is never long. (Only) in the interim where this theme is unavailable, I recommend NASA Night Launch.

I'd given up on themes Rated 5 out of 5 stars

I'd given up on themes, all of them seemed to me as simple and basic colour changes. Want flowers? or a animal? or maybe some cool art try my theme!?. They seemed so... basic. This one on the other hand is worth of the name theme the shapes and icon are all different. And it leads to a crisp clean modern look. 10/10

I absolutely love everything about this theme.

Great theme Rated 5 out of 5 stars

The only complete theme that worth the install on my side. As perfect under Windows as Linux, of course author may respond that nothing is perfect. But it's perfect to my taste and it's my humble opinion :)
Thank you so much steva for maintaining it since a long time. Never donated yet but it's the only theme I would like to contribute to, so I will. I remember older FT themes by steva, used byt thousands of users but abandonned because of lack of contributions. I'm sure it requires a lot of time, and I remember that themes authors are not forced to share their work with us. Don't give up steva! :)

Best theme ever Rated 5 out of 5 stars

Really love it. Would happily contribute but I cannot use paypal. Is there another service you can use?

I do wonder about the long term with regards to how/if this theme will continue to exist as Mozilla cleans up Firefox's code. If you have a few minutes would you mind letting us know your thoughts in the "About" section?

Thank you again for your wonderful work.
