    The Tor Browser team is proud to announce the release of the fifth alpha of the 4.5 series of Tor Browser. The release is available from the extended downloads page and also from our distribution directory.

    Tor Browser 4.5a5 is based on Firefox ESR 31.6.0, which features important security updates to Firefox.

    We're very excited about the usability and security improvements in this release. On the usability front, we've created a FreeDesktop-compatible launcher wrapper for Linux that can be invoked from either the GUI or the shell, and we also provide Windows users with the ability to add optional Start Menu and Desktop shortcuts. The circuit usage of Tor Browser has also been improved to avoid transitioning to a new circuit for a website while it is in active use.

    On the security front, the Security Slider now has full descriptions of the browser behaviors that are changed at each security level. We've also made improvements to our display resolution fingerprinting defenses to automatically resize the browser window to a 200x100 pixel multiple after resize or maximization, and to perform similar resizing for full screen HTML5 video. Finally, the Windows releases are also now signed using the hardware signing token graciously provided to us by DigiCert, so Windows users should no longer be warned about Tor Browser being downloaded from an "unknown publisher".

    And those are just the highlights. The complete list of changes since the 4.5a4 release is as follows:
