"A lot of people felt that Mozilla's code base was bloated, and that it would have trouble delivering a sleek, innovative mobile application. Since then, though, the company has put increasing emphasis on its plans for Fennec.
"While Fennec is available for use on some Nokia devices in an early alpha version, and there is a PC emulation version available for very early tests, it has not been released in a final, open source version for widespread use on various mobile platforms. As Mozilla confirmed this week, Chris Finke has added Fennec compatibility to his URL Fixer extension. At first glance, that may not seem like earth-shaking news, but the important thing to note is that URL Fixer was a Firefox extension. Henke forked it so that it works with Fennec."
