Make sure Service Pack 5 is installed. Use zipfile, the install program won't work. It also needs a newer OLEAUT32.DLL and an updated Common Controls dll file. Delete the nsSearchService.js and nsSafebrowsingApplication.js files in the Firefox folders. Create a file called userChrome.ccs with modified fonts and place it in the chrome folder. Should be good to go.
