Apt-Get Install Firefox Error: Package Has No Installation Candidate---Need Firefox for Selenium

Using apt-get install firefox I get:

Package firefox is not available but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'firefox' has no installation candidate.

I have already tried apt-get update which did add more packages but getting the same error.

I can manually go onto firefox through the desktop Firefox ESR icon and webpages work fine just not through the terminal. The firefox on my desktop is 52.6.0 but I need this upgraded to the latest for a script to run using selenium. Not sure if the desktop firefox even has anything to do with my terminal at this point.

Update: Also tried running apt-get install firefox-esr which did install but selenium still fails to use this. Seems to be looking for the original firefox not ESR version.
