how temporarily disable firefox
On my IMAC how can I totally turn off and disable firefox and then be able later to turn it back on? This will enable me to use safari without firefox popping up. Some sites only recognize my safari browser.

I'm not sure what you exactly mean, but you can close firefox at anytime.
If you mean how to set Safari as the default browser, see https://support.apple.com/en-us/HT201607 under "How to set a default web browser".
To later set Firefox back as the default, see Make Firefox your default browser
