I have updated Thunderbird to 68.3.1(32bit). In the past, unread messages were highlighted in blue., read messages were in white. I could tell them apart. With 68.3.1 in the Release Notes it says there has been a change so that in the Dark Theme, the Blue highlighted messages will no longer be highlighted that way and will be highlighted in a brighter white. Some people could not see the Blue highlighting. I cannot see the brighter white. My very strong wish, Please, Would you make it a choice ? It is no choice now. I feel I must live with it. I liked the Blue highlighting. I like the Dark Theme. Why do I have to lose both now ? Wayne
