Firefox looking up DNS issue

So so so slow...
Seem this issue can be fixed by starting a new profile. Here is the list of the Add-ons I installed
Start a new profile:
C:\Documents and Settings\Administrator\Application Data\Mozilla\Firefox
Open profiles.ini
Add
[Profile2]
Name=Frank
IsRelative=1
Path=Profiles/7bbtrocp.Frank

Open Firefox, Firefox will ask you to select the profile.
