MicroB on Maemo 4
|Developer(s)||Nokia's maemo project|
|Stable release||1.0.4 / December 17, 2008|
Engine under MPL/GPL/LGPL tri-license
It is shipped with Nokia's N800, N810 and N900 Internet Tablets, and is also available for the 770 via the 'Hacker Editions' of the operating system. In place of Mozilla's XUL-based user interface, MicroB uses the Maemo-native (GTK-based) Hildon API and widgets.
MicroB was initially released as a public beta for Internet Tablet OS 2007 on July 17, 2007 to allow 3rd party developers and community members to develop and port plugins, and help shape the development of the browser. It was updated several times before it replaced Opera as Internet Tablet OS's default browser with the release of Internet Tablet OS 2008 on November 18, 2007 with the N810.
MicroB is Mozilla-based and uses the Gecko engine, but a number of features are omitted due to platform-specific limitations. In particular, SVG support is disabled due to unacceptable performance, and XUL is not included to reduce size and decrease memory consumption. As XUL is not included, most Firefox plugins require porting and repackaging before they can be used with MicroB. In place of XUL, MicroB uses GTK and the Hildon UI toolkit to provide a native interface.
