I have a problem here on every machine (Windows/Linux). If you see that there was a new post in one of the topics of the forum (bold), then go in there and read it, afterwards go back to forum overview, the topic is still bold.

If I go into the post and then step by step back to forum overview, it works fine and everything is marked as read.

e.g.
In "Phoronix Forums" you see in bold "Site Diskussion", you go in there and read the new post, then you click on "Phoronix Forums" and the "Site Diskussion" is still bold

Is it just me on Firefox or does everyone have the problem?
