The one where threads are highlighted by staff, and ones that you have started/commented on.

I have it enabled for my browser, but I am finding that some of the threads I have commented on are not highlighted..

I don't know if it's just a problem with the extension, or it's something Staff can fix, but I just wanted to alert them.

Is anyone else having this problem?

Those extension aren't written by TexAgs. So maybe try the nerdery? I think the writer posts there some.
