I have a release of TB 102.11 installed that I use as my production mail. I have installed TB 114b1 to make sure I can easily migrate when TB releases 115. In TB 102.11 when a message is marked as "read" the font changes to normal while other unread messages remain bold. This does not occur in 114b1. The font remains bold even after the state of the message changes to "read". I've kept all my settings between the two versions the same so I can see the differences. So far this seems to be the only difference of any significance (at least to me). Is there a setting or configuration change I should be making that I don't know about? I should also point out that in Settings / Account Settings that bold seems to be the predominate setting in 114b1 while normal appears to be the predominate setting in 102.11. I also notice this behavior in the about:config panel. Any thoughts or help would be appreciated.
