If I get email like newsletter it opens in some kind of "editing" mode where I can change all frame/picture frames and non of the message links work. These frames are shown as red dotted lines. Originally everyting was normally but now this "mode" has come back without changing any settings in Thunderbird. I have already once removed whole program and all related folders and reinsall the program after which it was working normally for a while, but now this "mode" has turn on again. Hopefully the picture clarifies what I mean, as it is kind of hard to explain.
