was one of several readers to point out the release of Firefox 3.1 Beta
2, the first version of its flagship browser to switch on the much
faster TraceMonkey JavaScript engine and sport a working privacy mode
dubbed “Private Browsing.” An ancillary addition to Private Browsing is

developing specification that will let Web-based application developers

Beta 1 is gone in the new beta: Ctrl-Tab switching. According to the
developer, the UI needs more work; the feature probably won’t be in the
final 3.1.
