Thunderbird problem fixed + plus an additional problem

[Donald Leslie]

I renamed the Inbox fille and created a new Inbox. Thunderbird then 
downloaded everything and now only gets new messages. I did look at the 
popstate.dat file. Before it had a few "k" entires but was mostly "d". 
It now has only "k" entries since Inbox was rebuilt.

This had been more of an issues until recently since I can no longer use 
Comcast web-mail using firefox or konqueror. When you select the email 
tab at the Comcast web site the page goes away and then returns to same 
location not to email. I tried using Chrome a few days ago and 
discovered that it works fine. I wonder if it has anything to do with 
their  java script processing?
