Update: Please disregard. Just realized it was my FireFox History settings that were causing the issue. Silly me :)

I could swear that the UT behavior used to be that when you selected a message in the top pane, it changed color so you could easily tell which message was selected. I no longer see that. Now when I read a message in a thread I cannot tell in the top pane which message I am on. Message links in the top pane all stay the same color. Didn't read message links also change color so you could tell you read them? Is it my browser? A browser or UT setting? I haven't been in a while.

Now, the color change for "Visited Links" only works if I unselect "Allow pages to choose their own colors, instead of my selections above" in Firefox settings. If I let the pages to choose, then UT colors don't change for me. UPdate: actually even then the color of the links for the read messages do not change.

Using Firefox 22.0
