Thunderbird V 115.3.1

Hi ! this version is null. Please let us comme back to the previous one. Greetings

Going back to the prior version is not recommended (it doesn’t always work) nor is it supported. Please post your specific workflow problem in one of the links listed in ** READ ME NOW - before you post here in discourse - READ ME NOW ** for best results. Or post it here.

One reason: userChrome.css doesn’t work anymore. So I can’t change for example message pane background color.
