Now days it's more important than ever to stay secure while working or surfing the web. Bet You didn't know that many https sites you visit default to http instead, and even when You visit an encrypted site that many of the links on the site go back to UN encrypted sites. You can keep everything HTTPS all the time for free by using a tool by EFF...Elecronic Frontiers Foundation called HTTPS Everywhere. I'd be remiss to not mention another free tool they have created called Privacy badger. "Privacy badger stops spying adds and invisible trackers" tracking You.
These tools are available for Chrome, Firefox and (for Android) and Opera.
I'm grateful there are still unsung heroes out there like EFF.
