How to Open/Activate Web Developer Tools on Chrome, Firefox and Safari Browsers

As a web developer your browsers’ developer tools are essential. Here is how to view/turn on the developer tools on Chrome, Firefox and Safari on a Mac OS X. The process should be similar on other OS’s.

All Browsers

The easiest way to open the developer tools panel is to right click somewhere on the page and click on inspect element. If you don’t see that option then you may have to enable the tools (as in Safari below).
