I'm using Firefox 2.0.0.1 for most of my web browsing. Sometime in the last few months, I noticed that I lost two features of Flyertalk: the ability to post and the ability to go to the last read post in a thread. For grins, I logged on using I.E. 7.0, and I found that all the functionality was there. Is this a common issue with Firefox? I don't really know if this was something new with FF 2, or if it happened sometime later.

I've tried logging in and out and clearing my cache. They didn't help.
