I want to use firefox as my web browser, having a lot of problems with yahoo. Do i need to uninstall yahoo first or can i just download firefox also is firefox easy to uninstall, incase i have any problems with it?
If you are worried about uninstalling Firefox, if you don't like it, you could use the portable firefox.
Portable means that all the settings etc, are contained within the softwares folder. So if you don't like it, you can just delete the folder and it's completely gone. It also has the advantage that you can put the folder on a USB key and use it on someone elses computer, with your own favorites and settings.
Once you have downloaded the setup file, run it, a folder will be created containing firefox, just click it to run it. click here
