MicroB
open-in-new
<h2 id="history">History</h2> <p>MicroB was initially released as a <a href="/facts/Public_beta/z4Q4RElA">public beta</a> for <a href="/facts/Maemo/gQyp5ehf">Internet Tablet OS 2007</a> on July 17, 2007 to allow <a href="/facts/Third-party_developer/6gbHyvDu">third-party developers</a> and community members to develop and port <a href="/facts/Plug-in_(computing)/351Du3Wu">plugins</a>, and help shape the development of the browser.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> It was updated several times before it replaced <a href="/facts/Opera_(web_browser)/2NYCcTj1">Opera</a> as Internet Tablet OS's default browser with the release of <a href="/facts/Maemo/gQyp5ehf">Internet Tablet OS 2008</a> on November 18, 2007 with the <a href="/facts/Nokia_N810/emCL6z4X">N810</a>.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p> <h2 id="architecture">Architecture</h2> <p>MicroB is <a href="/facts/Mozilla/FevL9Itn">Mozilla</a>-based and uses the <a href="/facts/Gecko_(layout_engine)/HXINMkgW">Gecko engine</a>, but a number of features are omitted due to platform-specific limitations. In particular, <a href="/facts/Scalable_Vector_Graphics/ARq5C3YV">SVG</a> support is disabled due to unacceptable performance, and <a href="/facts/XUL/VoNXYx92">XUL</a> is not included to reduce size and decrease memory consumption.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> 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 <a href="/facts/GTK/oLpVm9pp">GTK</a> and the <a href="/facts/Hildon/nbGn7nWx">Hildon UI</a> toolkit to provide a native interface.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p> <h3>Add-ons</h3> <p><a href="/facts/Plug-in_(computing)/351Du3Wu">Add-ons</a> usually need to be <a href="/facts/Port/4Uuw6Fec">ported</a>. The Maemo Browser Extras project is responsible for a large number of the available add-ons.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> </p> <h4>Some MicroB Plugins</h4> <ul><li><a href="/facts/Adblock_Plus/Q4BhH6wQ">Adblock Plus</a><a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a></li> <li><a href="/facts/Adobe_Flash/3Lrp9JuH">Adobe Flash 9</a> (bundled with Maemo)</li> <li><a href="/facts/Flashblock/JQe8aqQT">Flashblock</a><a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a></li> <li><a href="/facts/Gears_(software)/JoU3oU8I">Gears</a> (partial functionality)<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a></li> <li><a href="/facts/Greasemonkey/tvlvx5qB">Greasemonkey</a> – All scripts that work on the desktop version of Firefox work fine in MicroB, extending the capabilities of the browser and even replacing the need for some extensions which are not available for MicroB.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a></li> <li><a href="/facts/MPlayer/nfyW0yjn">MPlayer</a> plugin<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a></li> <li><a href="/facts/Windows_Media_Player/k6xxSATq">Windows Media Player</a> Stream and <a href="/facts/RealPlayer/IjS4t5h8">RealPlayer</a> stream supports via the built-in Media player</li> <li><a href="/facts/Wireless_Markup_Language/2Ua3u1Cw">WML</a> browser<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a></li></ul> <h2 id="notes">Notes</h2> <ul><li><a href="http://browser.garage.maemo.org/docs/browser_paper.html">Mozilla based browser for maemo whitepaper</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="http://browser.garage.maemo.org">MicroB Homepage</a> <a href="https://web.archive.org/web/20080421150125/http://browser.garage.maemo.org/">Archived</a> 2008-04-21 at the <a href="/facts/Wayback_Machine/nmQ3a6JC">Wayback Machine</a></li> <li><a href="http://browser-extras.garage.maemo.org/">Maemo Browser Extras</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Mozilla based browser engine available for testing MicroB beta announcement <a href="http://browser.garage.maemo.org/news/1/" target="_blank">http://browser.garage.maemo.org/news/1/</a> <a href="#fnref:1" class="footnote-back-ref">↩</a></p></li> <li id="fn:2"><p>MicroB ships as the official browser for IT OS 2008 <a href="http://browser.garage.maemo.org/news/9/" target="_blank">http://browser.garage.maemo.org/news/9/</a> <a href="#fnref:2" class="footnote-back-ref">↩</a></p></li> <li id="fn:3"><p>MicroB whitepaper - 4.3 Supported web standards <a href="http://browser.garage.maemo.org/docs/browser_paper.html#s4.2" target="_blank">http://browser.garage.maemo.org/docs/browser_paper.html#s4.2</a> <a href="#fnref:3" class="footnote-back-ref">↩</a></p></li> <li id="fn:4"><p>MicroB whitepaper - 2.2 Browser User Interface <a href="http://browser.garage.maemo.org/docs/browser_paper.html#s2.2" target="_blank">http://browser.garage.maemo.org/docs/browser_paper.html#s2.2</a> <a href="#fnref:4" class="footnote-back-ref">↩</a></p></li> <li id="fn:5"><p>Browser Extras <a href="http://browser-extras.garage.maemo.org/" target="_blank">http://browser-extras.garage.maemo.org/</a> <a href="#fnref:5" class="footnote-back-ref">↩</a></p></li> <li id="fn:6"><p>Adblock Plus Plugin <a href="http://browser-extras.garage.maemo.org/news/5/" target="_blank">http://browser-extras.garage.maemo.org/news/5/</a> <a href="#fnref:6" class="footnote-back-ref">↩</a></p></li> <li id="fn:7"><p>Flashblock Plugin <a href="http://browser-extras.garage.maemo.org/news/7/" target="_blank">http://browser-extras.garage.maemo.org/news/7/</a> <a href="#fnref:7" class="footnote-back-ref">↩</a></p></li> <li id="fn:8"><p>Google Gears Plugin[dead link] <a href="http://www.internettablettalk.com/forums/showthread.php?t=17174" target="_blank">http://www.internettablettalk.com/forums/showthread.php?t=17174</a> <a href="#fnref:8" class="footnote-back-ref">↩</a></p></li> <li id="fn:9"><p>Greasemonkey Plugin[dead link] <a href="http://browser-extras.garage.maemo.org/5" target="_blank">http://browser-extras.garage.maemo.org/5</a> <a href="#fnref:9" class="footnote-back-ref">↩</a></p></li> <li id="fn:10"><p>MPlayer Plugin Archived March 15, 2008, at the Wayback Machine <a href="http://www.internettablettalk.com/forums/showthread.php?t=17715" target="_blank">http://www.internettablettalk.com/forums/showthread.php?t=17715</a> <a href="#fnref:10" class="footnote-back-ref">↩</a></p></li> <li id="fn:11"><p>Wmlbrowser Plugin[dead link] <a href="http://www.internettablettalk.com/forums/showthread.php?p=197015" target="_blank">http://www.internettablettalk.com/forums/showthread.php?p=197015</a> <a href="#fnref:11" class="footnote-back-ref">↩</a></p></li> </ol>
