"TT DeepDark" extension update for Thunderbird 68

Hello everyone,

I am Stefano Rosselli , a freelance illustrator and visual designer based in Geneva (CH). I am raising funds to support the port of my add-on "TT DeepDark" for the current version (v68) of the free email application called Thunderbird.
For those of you who don't know my add-on yet, "TT DeepDark" is an add-on which transforms the overall look and feel of Thunderbird. It turns the user interface into a dark color scheme (more completely than the default Thunderbird dark theme does).

Back in September 2019, Thunderbird received a major update and due to the main changes brought to the software, my add-on is no more compatible and needs to be rebuilt.
This will require to invest at least about 150 hours of work so I could be able to offer a new version to the numerous users around the world who rely on my add-on (about 30'000+ daily users).

Since this is a personal project which I am not paid for (I only receive time to time micro donations by a few users), if I keep on using exclusively my free time, I will need months to deliver an updated version. From another end, I can't afford to loan my freelance working hours without receiving a minimum of financial support. That's why I opened this campaign, so I could have the possibility to use my working timetable to drastically increase the update pace and offer a new version of my add-on much faster.

The fact to be able to keep on working on this project means a lot to me, because it is a way to use my design skills on a large scale to improve many people user experience when interacting with Thunderbird, especially for persons which eyes are sensitive to light. It also gives me the opportunity to bring my modest contribution to the Thunderbird's open source project.

By supporting this campaign, not only you will contribute to keeping my add-on alive, but also accessible for free for anyone around the world and totally free of ads.

Big thanks in advance to each of you who will support my work!
