  • Yep this is my all time fav theme, been using it for years too. Eagerly waiting for the update!
  • The theme offers a sleek and minimalist dark take on Firefox. It is concise in what details are skinned and particular about the way they are skinned; the theme is consistent and offers a generally good design. Not only does the theme come as such, but custom style scripts can be applied to match the theme. For dark theme lovers, this is the perfect Firefox theme.
  • отличная тема.
  • Best theme ever. Waiting for firefox 57 update
  • By far the best theme for Firefox. I have been using this for years and years, cant wait for the 57 update.
  • I've used this theme for years. Thank you for maintaining it and always staying on top of version updates. You've given my retinas at least 5 extra years. :)
  • The only reason why i am using FIREFOX for years is thank to this fantastic theme
    FT DeepDark...good work Steva
  • This is one of best FF skins i've ever used, can't wait for mozilla to allow themes for v57+.

    Keep up the awesome job Steva, you're great!
  • Using this for years, definitely the best theme out there. Just came here to say "Thank You". Now i am totally ready for you update version. :)
  • hurry up :)
  • For me, the best theme for Firefox and it miss me a lot!!
    Thank you in advance for your work in order to keep on proposing your theme as an official AMO "add-on".
  • I love this theme. I hope for a Firefox Quantum release.
  • Love the dark theme and missing it on the new version.
  • This is the best dark theme. I spend countless hours online for personal and work and do not like too much light into my eyes. None of the other dark themes are complete. Eagerly waiting for Firefox 57 support!!
  • Incredibly awesome theme. I really like the color scheme. It is very appealing and easy on the eyes. I only have dark themes on the browsers I use at home, work, and school. Thank you for the additional information about tweaking, work-arounds, and the future of your theme with FF Quantum. You rock!
  • nice
  • Muy buen complemento da estilo al navegador.
  • I get it, that it's impossible right now, to implement an updated version, but isn't there any option with userChrome.css or something like that?

    Developer response

    Indeed, the browser UI can still be customized through the use of custom "userChrome.css" and "userContent.css" files. But it has many serious downsides which, for the moment, are preventing me to definitely go this path.
    I will only consider if to propose a "userChrome.css + userContent.css" combo once Mozilla will release the new theming system and, of course, once I will have these kind of files ready for public release. I already started to customize my own Firefox thanks to this workaround, but it is still a work in progress.

    I would like, first, to see If the new theming system will be able or not to offer satisfying visual customization possibilities. If I see it can't offer a comparable experience as former complete themes, I may try to find a way to distribute a "userChrome.css + userContent.css" package outside the Mozilla add-ons website.
    But honestly, I would really like to keep on proposing my theme as an official "add-on" on AMO website. In my opinion, it would be the best solution.

    In the meantime, if you still want to keep on using my complete theme, there is still the possibility to install Firefox ESR. It will allow you to use my complete theme at least till next summer. By this time, we'll have better picture of the new theming system for Firefox Quantum.

    By the way, next time, please, use the "support email" and not the review section to ask questions, as it is not the place where to do it. Thanks in advance.
  • Best addon ever.
  • What is your Twitter account for updates? EDIT. OK I found it further down thanks. https://twitter.com/stefrosselli

    Developer response

    Unfortunately, as stated in the add-on description, it is impossible for me to update this add-on for Firefox 57+. Indeed, it doesn't allow anymore the use of complete themes.
  • It's too coll!!
    I have stopped upgrading to quantum because I can not use this theme.
    I want to use this in quantum.

    Developer response

    Unfortunately, complete themes can't be installed on Firefox 57+. The browser doesn't allow this kind of add-on to be installed anymore. Because of this, I can't update my theme for Quantum.
    There will be need to wait for Mozilla to release their new theming system and to see what it can offer as visual customization. Like you, I will have to wait.
  • Love the dark menus and overall slick, simple look! Mozilla needs to allow possibilities to update this for FireFox 57, I miss my FT DeepDark theme!

    Developer response

    A new theming system is supposed to be released in 2018. It may help me to port my add-on to the new Firefox. Let's wait and see
  • I need a Quantum version now! It doesn't work on Firefox Quantum (v.57).

    Developer response

    Unfortunately, I can't update my add-on for Quantum for the simple reason that Firefox doesn't allow anymore to install this kind of add-ons.
  • Best theme ever. I only wish this was compatible with Firefox Quantum :(
