It's a good idea to view pages in both of the major browsers. When a "Document Window" is open, you can press [F12] to view the page in the primary browser or [CTRL+F12) to view the page in the secondary browser.

To designate primary and secondary browsers, {Click} the "Preview in Browser" category in "Preferences".
