firefox 1.5 problem

[Charles Malespin]

Hi all, I just installed firefox 1.5 using the wiki on the ubuntu
website.  Everything is going fine except for one small problem.  Say Im
at the slashdot.org website and I click on my drop down menu that shows
all the sites Ive entered(not the history, I just dont know the exact
word for it...).  If I pick a site, say google, from the drop down to go
to it from slashdot(or any site) it just reloads the site that I am
currently on.  It doesnt take me to the site that I picked from the drop
down.  Is anyone else experiencing this?  I have to retype the address
in the address bar, it wont let me go there from just clicking the link
on my drop down.  Its very frustrating cause thats the only problem I
have with 1.5 ... help?  
Thanks, 
Charles
