Very nice work, balanced art and colour match Rated 4 out of 5 stars

Most black themes for thunderbird look weird. This one isn't. Colors are balanced, and even though in black there isn't much to see, in this particular add-on the greys and blues seem to match all together to a spectacular art result. Congratulations!
The only disadvantage is that after so many user requests to support new versions of thunderbird new versions just seem to delay.

Thank you very much for this nice review of my work! :) I m glad you appreciate it. There is just one thing I find a bit misplaced, it s the fact that you are criticizing the fact that it has not been updated til now. You have to remember that in lots of cases, addons developers are doing that job for free beside all what they already have to do. I need first to concentrate on other jobs and also to have a private life, before I can work on themes. I would love I could work more on my addons, but for the moment I can t afford that. So even if lots of users are asking me to update for TB12 that doesn t mean that it will help me in having more free time to work on it.
Thanks again for the review and for understanding

Waiting for Thunderbird 12 compatibility Rated 5 out of 5 stars

I love this theme so much I will not update to T12 until DeepDark is compatible

Excellent Rated 5 out of 5 stars

I love this theme and have been using it for ages, unfortunately I have just updated to Thunderbird 12.0 and it got disabled! I hope that it will be updated at some point because now my Thunderbird looks naked, cold and bleak without it! ;)

Could you make unread messagess stand out a little more? Rated 5 out of 5 stars

Love it, and use it as my current TB theme. One suggestion: maybe it's just me and my old, tired eyes, but I'd wish unread messages were highlighted even stronger, since the bold type doesn't help to differentiate them much from read messages (at least to me). Not a deal-breaker, though. :)

Try version of my theme

Thanks for your review :) I m glad you appreciate my work and that you are using it.
Concerning your request, lately already few users asked me the same, so I uploaded a new version ( with a blue font for the unread messages. Did you install it or you are still running previous version ? In case you still didn t install it, here is the link >

Really nice Rated 5 out of 5 stars

This is the best theme for Thunderbird Ive ever found.
But it would be very helpful if the unread messages would be highlighted in the blue color, like the selection font.

Rated 5 out of 5 stars

Love this theme, readabillity in awesome! Reminds me of PS6 beta :)

Would love to see email content ( plus conversation plugin ) in same colors. I guess i have to style it myself.

Great!! But... Rated 5 out of 5 stars

Just installed 1.6.3 on TB 11.0 on XP.

I agree with most everyone here! I love the theme! My wife isn't so sold on it yet.

However, we have multiple accounts and it would be ever so nice if it was easier to be able to tell which account had new eMails and then somehow better highlight the new eMails.

Still, it's a simply terrific look!!! Keep up the great work!

Make new emails a diff. color PLEASE Rated 5 out of 5 stars

Love the theme, my only complaint is that it is hard to tell the new emails apart from the rest, please fix!!

Dark themes are by far to rare for TB! Great work!

Great Add-On! Rated 5 out of 5 stars

I absolutely love this add-on! It gives my screen a break from the otherwise "boring" normality of my desktop and inspires creativity.
It was a little difficult at first for my eyes to immediately register the unread emails from the others but the more I've used it, the more I love it.
I'm new to Mozilla Thunderbird. I was previously using Microsoft Outlook and switched because to me, Thunderbird makes it easier to organize my emails. I was disappointed at first with the layout of Thunderbird compared to Outlook but soon had it customized with great add-on's including this one and I wouldn't go back!

Hard to tell which folders contain new mail Rated 5 out of 5 stars

I really like this theme, but I find it hard to know where new mail is. I have lots of folders with sub folders. The bold folder name indicates new mail is present in that folder or a sub folder, but I find this hard to distinguish from a normal unbolded folder name. Can you make it so that the little yellow sunburst icon is present on all folders that contain new mail not just the top level one?

Elegant Dark Theme - Finally! Rated 5 out of 5 stars

Fantastic dark theme for Thunderbird - Finally! Excellent contrast between the dark grays make for an enjoyable dark theme that is easy on the eyes. However, for some implementations (or monitors) it may be a bit dark. (especially on Plasma or LED-LCD displays). Perhaps a "TT DeepDark (light) is in order with the brightness bumped up just a few shades. After years of using dark GTK themes in Linux to get the desired dark theme needed in Thunderbird, this theme makes tbird look almost as good under windows :)

Rated 4 out of 5 stars

Very nice. I find the inbox view being very dark throws off all my tags, based on the normal white on black view. It is a little harder to see.

Having the message window down the bottom in bright white really clashes with the rest of the theme but that said it's pretty and I will try it a few days to see if I get used to it - but that's me not your work. :)

This review is for a previous version of the add-on (1.4.1). 

Thanks for your feedback :) Concerning the window down, you can set by your own the color you like (as the font color too). White is the default one, but you can change it. I didn t touch that part, because it s up to users to chose the color they like in the options panel. You can also set the color of the mail compositor.

Minor issue with drop-down menus Rated 4 out of 5 stars

First off, this is a very beautiful theme. Very well done.
But there's a bit of an issue with the drop-downs (File, Edit, View, etc and Right-Clicking as well). The program will act like there is a menu, but the menu does not actually become visible. For example, if I clicked File, the word itself will turn blue, indicating that it's active, but no menu is actually visible. If I move the pointer along the bar, the other words will also change to blue. If I click in the area where the menu ought to be, then does what it would normally do. The only issue is that I can't see it.

I haven't seen anyone else mention this issue yet, so I'm wondering if it could just be me or if no one else has realized it yet.

I use Windows 7 and I just downloaded Thunderbird not too long ago, so it should still be a recent, if not up-to-date, version.

This review is for a previous version of the add-on (1.3.5). 

Thanks for your review :) I didn t notice any problem when clicking on the menu buttons. They all display the drop-downs. By the way if the theme had such issue, I think that Mozilla's reviewers would already inform me when they checked my work, because it s not some little issue when a dropdown doesn t display correctly. The problem should be somewhere else.
I don t know if you noticed in the addon description but now there is a short text to describing few things to do when facing an issue and, among them, what is very important so I could understand well what is the problem is to provide me a screenshot or a short video. Like this I m sure we are talking about the same thing. But still, I really don t see why you are facing that issue, because I never noticed any problems with the dropdowns and no one else told me about it.

Edit : when you rollover a menu which is active in the main menu bar it s supposed to become blue, but when you pass on an inactive menu I don t know if you noticed but the color is white and after that it closes the dropdown. So I think that what you are trying to describe is when you rollover from an active to an inactive menu then the dropdown disappear. It s a normal behavior, the default theme do that too. Maybe what I could just simply do is to make more difference between an inactive and active menu. But try with the default theme, you ll see that s the same. So it s not an issue, it s simply that inactive menu when not hovered should be a bit darker so we could better notice they are not active. I ll change little bit the inactive menu font color in the 1.3.7 version which will be uploaded soon.

Awesome theme, minor glitch. Rated 5 out of 5 stars

Like the theme very much, thank you for the theme. Just a minor glitch (I'm not sure if this just happen to me only)... I'd sort all my mail in inbox and group them by date. And it seems bizarre that group title (in my case: 'today' / 'yesterday' / 'last week' / 'old') appeared in white colour pretty 'random'. Here is the screen captured:

It will be fixed with the next update ;)

Hi there,
Thanks for your review. I fixed that before for a previous version, but it seems I touched something with the last update and it came back. I ll fix that with the next update. it will be ok with the 1.3.6 version.
Thanks for your message.

Great theme, but could it be a little lighter ? Rated 4 out of 5 stars

Thanks for a great theme for Thunderbird. I enjoy dark themes a lot. I only find this one is a bit too dark for me. Let me explain.

I'm using a great dark Windows Seven theme called SkullTrail ( ). IMHO it's a perfect dark theme, with good colors and excellent contrast.

I'd love to see TT DeepDark or another theme that would be closer to SkullTrail (thus a bit lighter). What do you thinks ?

Thanks again & Best regards. :)

Thanks for your review :) Indeed, maybe it could be something good to make the theme a bit brighter. With my screen and my brightness settings it looks good, but I guess it s not the same for everybody. I ll have a try when I ll have a bit more time. I need to change lots of code to modify everywhere the dark color and maybe I ll need also to make the font a bit brighter if I do it. So i ll need hours of work to do this simple change, because they are lots of code to modify and I need to be careful to apply the changes everywhere. Til then the theme will be in his acutal color, but I ll have a try and see if it s ok.

Best ever Rated 5 out of 5 stars

It's awesome! Love it!
I use Thunderbird for couple of years now.
I have never found as nice looking theme as TT DeepDark is, not just that, it also fits my personal color / style taste -.-

There was always something missing by other Themes. However as already said, this theme is amazing!
I suggest it to all, who like dark themes ;)

steva, you just gave me an early Christmas present hehe
Thank you! xx

Great Theme - please add a white version Rated 5 out of 5 stars

Amazing work - really unique and stark! Not just another Mac or Aero theme.
I only wish it came in white as well.

Great, but one problem when filtering. Rated 5 out of 5 stars

Easily the most aesthetically pleasing theme for TBird, in my humble opinion. Leagues better than the competition - especially since there's a matching Ffox theme!

UPDATE: I WAS having a problem with version 1.3.4, but after describing it here, the problem has been fixed in the new (experimental) version 1.3.5. The fix looks great and is quite usable.. Praise for the quick fix. That was the only thing missing for 5 stars!

Thanks for your review :) Regarding the filter buttons, I think that they are clearly highlighted, at least on my computer it s showing quite well. Here is a link so you could see how it should look
I think that the dark background is making the highlighted filter to show up quite well on the blue bar? But maybe there is a little problem with the Linux version ? I ll have to check again. The screenshot I provided is on Win7. It s suppose to look like this.

Edit : Just try to install the version to see if it solves something. Here is the link for download >
