Speed up load time - Firefox is slow to load initially on Windows XP. You can speed this up a bit by using XP's built in prefetcher. Simply right-click on the Firefox icon you use to start the browser. Add the text /Prefetch:1 to the end of the line in the target field.
The whole line should look something like the following:
"C:\Program Files\Mozilla Firefox\firefox.exe" /Prefetch:1
