Fork of the Account Colors add-on for Thunderbird
Continuation of the account colours plugin for modern thunderbird(s).
The addon no longer works. Quite a bit of changes to Thunderbird and to be honest unless you are working with addons for Thunderbird regularly, its impossible to keep up with all the breaking changes.
I don't have the time, but will keep the repo open in the hopes of a PR from someone with more time and knowledge.
