Rated 5 out of 5 stars

My apologies to the developers and Farbige Ordner. I received a super fast response to my first post, I only posted it as I had no idea what else to do. The developers are working on a solution to my problem.
Fantastic help and great service.

This review is for a previous version of the add-on (1.2.5.2).

This is not working for me. Very please to see this finally out but it is not doing anything. My folders remain the same default colours. Should I be doing anything extra ?. If yes please help me freebeerjkt@gmail.com.
----------------------------
Thanks for the fast reply and REALLY appreciate the help.
Problem is I right click on a folder and choose a color but the folder remains exactly the same, no changes.
I am running Win10pro, latest version. Thunderbird portable version 68.3.1.
A list of the other add-ons can be sent if I am givine an email address to send them to.
If you need anything else please just let me know.
Best regards,
Tony.
Thanks in advance.

This review is for a previous version of the add-on (1.2.5.2). 

First of all I don't appreciate you downvote this Add-on before you even give my ANY chance to do anything.

Second : Provide usefull information - See, my crystal ball is currently broken so unfortunately you'll actually have to post it digitally.

Informations that could be usefull :
What version of TB do you use ?
What operating system ?
Do you have any other Add-ons or themes installed ? If yes : which ones ( list them ) ?

See i'll have to reproduce your setup and thus the error itself in order to analyze and understand it in the first place.

Have a good day, sir.
