You must download the new release for the Tor Browser, Tor Browser 4.5, that was designed with a variety of improvements. The developers at the Tor Project have introduced a number of security, privacy and usability enhancements in the Tor Browser 4.5.
On the privacy front, the Tor Browser 4.5 improves the first party isolation feature that is designed to prevent third party company tracking online activities of the Tor users.
“First party isolation provides the property that third party advertisements, like buttons, and “mashup” content that is included on one site will only know about your activity on that site, and will not be able to match it to your activity while you are on any other site. In other words, with first party isolation, Facebook, Twitter, and Google+ can’t track you around the entire web using their infamous like buttons.” reads a blog post about Tor Browser 4.5.
Additionally, the Tor Browser 4.5 improves the resolution and locale fingerprinting defenses, developers have disabled the device sensor and video statistics APIs.
On the security front, the Tor Browser 4.5 comes with a new Security Slider designed to provide a user-friendly vulnerability surface reduction and allow users to choice the proper security level.
