Gmail Loading Problem in Firefox 3

Couple of months ago,  I have posted about a problem which I was having with Gmail and yet I’m about to post a new one. 

I’m sure everyone has noticed that progress bar after you enter your account information in login form.  I don’t know how long it has been since gmail put that loading bar. This is one of the problems I’m having with Gmail in Firefox. 

Here is the screen shot. It stops at that very end of the bar and it doesn’t go trough. At first, I waited bit more for it to load but didn’t go through. I tried clearing cookies, browsing history and other private data but it didn’t work. Only thing that works is that you have to hit “refresh” button.  Either it stops at the end like that screenshot or it never starts loading. 

I’m going to try to reinstall Firefox 3 if this keeps being a problem. I’ll also update this post if anything works. Gmail works fine with other browsers. I don’t get this problem in Safari, Opera, IE7.
