Whether I try to open up Firefox by clicking on the shortcut link on my desktop,
or I open up a link from within an already opened Firefox page, all of Firefox
stops responding for 10-30 seconds. I am not having this problem with IE, so i
know that it isnt a problem with my computer/internet connection. I also know
that i dont have a virus, any adware, or any spyware. This startd happening two
days ago. I have had firefox for quite some time and have never had this problem
before. I tried to uninstall and reinstall the software, but it just replicated
teh old files. (it was like i had never uninstalled it) Every now and then it
will hang too long and cause the program to timeout and force it to end task. 

Reproducible: Always

Steps to Reproduce:
1.Open up Mozilla Firefox from desktop shortcut, or executable in Mozilla
Firefox folder. (Bug occurs)
2. Surf the web
3.Open up a link in a new page. (Bug occurs)

Actual Results:  
My Mozilla Firefox becomes unresponsive for 10-30 seconsd. All other open
processes work fine.

Expected Results:  
Opened up right away and let me surf the internet without having to wait.

I had exactly the same issue. After removing the proxy extension it now has no
delay at all. Hopefully it'll work for you too.
I think the first time this happened it lasted a couple of days and the way I
got around it that time was to choose the 'safe mode'  from the start menu.
Fingers crossed that it's cured this time.

I got the lag down to less than a second, so now it isnt that annoying. 
Hopefully when I restart my comp that lag will go away too. :)

Uninstalling Switch proxy seems to have cured my problems too.  Shame it was a 
great tool and has worked well until recently.  No doubt another Microsoft 
patch has interfered.

I have narrowed down the problem to the autoupdate feature of the SwitchProxy
tool. When I turned this off, the problem went away. Probably the server was
down because the website was unaccessible as well. Now there is a new website up. 

So in short, this was not a firefox bug at all.
