The "Beta" channel is up to six weeks behind the "Aurora" build, for up to about twelve weeks compared to the most recent "Nightly" build. As of version 35, the "Aurora" channel has been renamed to the "Developer Edition" channel. The "Aurora" build is up to six weeks behind "Nightly" and offers functionality that has undergone basic testing.

The native PDF viewer in Firefox could help protect against some of the ongoing attacks that use vulnerabilities in Adobe Reader and other PDF readers as infection vectors.Īttackers have been preying on Reader and Acrobat vulnerabilities for several years now, although the sandbox that Adobe added to Reader X and later versions has helped protect users against many exploits.
