After a healthy alpha (and pre-alpha) period, Mozilla is taking the mobile version of Firefox 4 to beta on Android and Maemo
this week, promising improvements in stability, performance, and
functionality. Actually, this represents a shift in branding for Maemo,
where Firefox 1.1 has already been gold for some time -- but odds are
good you're going to want to upgrade in any event, since this new
version nets you the so-called Layers framework that aims to improve
scrolling and zooming responsiveness. As you might expect, you get
built-in Firefox Sync -- basically making this a superset of Firefox Home -- and support for HTML5. Makes that ol' N900 look a little shinier, doesn't it?
I love their desktop browser(thanks Pepz) so I welcome any improvements they bring to the mobile platform, although I have no complaints with the native browser.
