How do I make Firefox 3.5 open faster? I love FF but use IE8 when I want to get on fast because it opens faster...I'm running Windows Vista, Home Premium.
If you have any add-ins installed, they can drastically increase the amount of time FireFox takes to load up.
Start by disabling all of the add-ins. Then enable them one at a time in order of priority to you. Stop when the amount of time it takes to start is as long as you are willing to put up with.
Just continue to use it. Superfetch will learn that you like to use Firefox and preload it into memory so it starts faster.
This worked for me:
Basically, clear out these folders (exact location names might vary for Vista):
C:\Documents and Settings*user*\Local Settings\History
C:\Documents and Settings*user*\Local Settings\Temporary Internet Files
C:\Documents and Settings*user*\My Recent Documents
C:\Documents and Settings*user*\Temp\
Cut my work firefox startup from about 20secs to 5 secs on XP (a mature installation). No difference on new install of Win 7 at home, but then there's been no time to build up crap in the relevant locations.
