Rated 5 out of 5 stars

Although i like the traditional Mozilla Thunderbird interface, I thought I'd give this developers theme a go and much to my surprise it literally transforms Thunderbird's slightly washed out and dated appearance and makes it look very modern and sleek indeed.

Yeah, its got room for improvement, but so far this looks great.

If you are someone that likes the sleek modern look you owe it to yourself to give this a whirl as it blends in well with Windows 10.

It even appears to look better than the premium outlook and looks and performs light years ahead of Windows 10 Mail.

So download Thunderbird and install this theme and also install an add-on called 'Account Colors' and you're set.

This review is for a previous version of the add-on (11.0.4.1).
