isBrowserSupported() function (that returns true if specified browser supports Session History Management) defined in javascripts/externals/epoch.js is outdated. It only matches Chrome versions 5+ and iOS browser versions 5+. Although, since many more browsers currently supports SHM (http://caniuse.com/history), it's time to update it.
This is currently by design to limit browser testing. When we first launched with this feature we were overrun with bugs and wanted to contain them better until the feature was more polished. The reboot of the Firefox OS app will be a catalyst in pushing this feature forward.
