I don't like the Firefox Web browser, and I prefer to use something else.
How can I remove it and use a browser of my choice?

There can be some packages that depend on (or recommend) a browser, in the form of a virtual package (
firefox provides the virtual packages
gnome-www-browser) or through an alternative (some package depends on
firefox | chromium-browser).
To solve your problem you can use
aptitude that provides more choices to as to proceed. The package
aptitude is not installed by default, so you need to install it
sudo apt-get install aptitude
then you can do
aptitude --simulate remove firefox
and see what it suggests. This is what it says on my system
enzotib@laptop:$ aptitude --simulate remove firefox The following packages will be REMOVED: firefox 0 packages upgraded, 0 newly installed, 1 to remove and 19 not upgraded.

This way you can see removing firefox what packages breaks. If you choose
n, another possible solution is suggested, ans so on.
When you have a best understanding of the problem, and you have selected your way, run
aptitude without the
Your original (unedited) question mentioned Firefox crashing constantly. You could try installing the latest stable release via PPA:
I personally use Firefox but I have also installed another browser for trouble shooting purposes it is always a good ideal to have more than one browser .
But if you want to uninstall Firefox open a terminal:
sudo apt-get autoremove firefox
sudo apt-get install chromium-browser
Or install what ever Web Browser you want to use. At which point you would then remove Firefox which should make the browser you installed the default one.
