Browserism is a little app that helps you quickly switch your Mac's default web browser. Out of the box it supports Safari, Chrome, Firefox, and Opera. You can add up to 4 additional browsers as well.
Use a different browser at work than you do at home? Browserism can schedule your work browser to activate at 9:00 AM and your personal browser to active at 5:00 PM (or whatever your work schedule is). Any time you have a need to switch your default browser, Browserism is the quickest and easiest way to do it. No more looking for hidden or hard-to-find settings and menus! Browserism supports OS X Yosemite's dark mode, and Retina displays.
