Basically, the latest Firefox Beta for Windows, Mac and Linux is ready for download and testing, and Do Not Track will now sport a trio of different options, namely “Do Track,” “Do Not Track” and “no preference”, where these are made available to the end user in order to better represent the user’s choice to opt-in or opt-out of online tracking. For those who want to gain access to the Do Not Track options, just indicate your preference by clicking on “preferences” followed by “privacy.”
You are also able to restore thumbnails on new tab page, which is a rather nifty feature as there are times when one can accidentally close thumbnails. Should that happen, there is the handy “undo” option that will restore said thumbnail.
