The MicroB web browser is the default web browser for the Maemo operating system. For the most part, its developers have done a good job of integrating it into the Maemo environment, but certain aspects that are not expected to be seen by everyday users have some glaring lack of polish, such as the plug-ins dialog which looks to be holding onto its antecedent toolkit (possibly XUL--despite the product itself not supporting XUL in the browser).
MicroB sometimes has problems such as being non-responsive or stalling. In bugs filed against it at bugs.maemo.org, the suggestion has been to clear history and cache--although the specific bug with these recommendations should have been fixed with the first Maemo update of 2010.
