Installing extensions really is easy. But you should take a few seconds on the privacy settings and expand the hidden check boxes.
As you can see, you can configure if the extension should be active when surfing an https website and if it should be active when in private browsing. The former is enabled by default, the latter not. That way you do not need to worry that extensions will scan your very private and secret online banking https pages when doing private browsing. I like a lot a lot the vision and care put into those two settings by the developers!
Extensions may require their own settings. In case of Ghostery I just selected all blockable scripts.
Before After Comparison
So, what do I get when using these three extensions? Here’s a before after comparison. Take a note of Ghostery’s popup on the top right listing the blocked scripts.
One More Thing
The following screenshot of the extensions I got installed also lists the Google maps full screen extension. That nifty extension adds a button to the Google Maps controls that can toggle the map view to full screen within the browser window. Upon loading Google Maps that full screen mode is entered automatically hiding the top and left control bars and providing you a big map. That is just great!
