I am being put off from upgrading firefox because a program called 'Babylon' tries to take over my firefox search page each time I attempted to upgrade. I have managed to get rid of this but it caused me a lot of time, delay and hassle that I did not need. So now I am unhappy about upgrading firefox as this thing manages to keep on re-attaching itself each time I do. My computer is also slower now for the first 5 or ten minutes of boot up.
