I find if you use gamebooster it'll help smooth the meter out a bit. A good reg cleaner is also a plus. i also use a program that refreshes my ram, it's called freeram xp pro. it works for all os's. Some people will say to delete whatever is in your prefetch folder. These are just somethings that can make your game a bit better. If your having probs with just firefox that's a whole other story. Try uninstalling the current flash player and installing version 11.2 and clicking the box that says let me decide to update or not. This has helped me out alot as well. best of luck to you and have fun.
