Firefox is a commonly used internet browser and can run on PCs, Mac books, and some tablets. This browser is known for its wide range of add-ons and is also less likely to be infected by malware than Internet Explorer. However, if you're having trouble with this browser or because you've never used it, you may want to uninstall the entire program.
