View Source Switch

View Source Switch View Source Switch is a Firefox add-on that allows one click switching the active tab between "view source" and regular web page.

How does it work ? Once the add-on is installed, a new icon appears in Firefox toolbar.

Click on it to switch to the view-source of your active tab. Click again to switch back to the regular view.

Instead of clicking, you can switch page with a keyboard shortcut. The default one is Ctrl + Shift + U / command + shift + U.
This key combination is intended to be similar to the Firefox built-in shortcut to view source in a new tab.
However, this key combination can easily be changed in the Firefox add-on menu

You can change the color scheme used for syntax highlight as well as the line wrapping in the extension preferences
