Moving on from December’s Beta 3, Mozilla has updated its work on Firefox 4 for Android and Maemo phones to Beta 4, bringing new features, bug fixes, and some supposedly impressive speed boosts.

The speed improvements are probably going to be the most noticeable to users upgrading from Beta 3, with what Mozilla claims is a 15% boost in JavaScript performance. Considering the ubiquity of JavaScript, you should find many sites becoming more responsive. You can also look forward to a smaller memory footprint and reduced CPU utilization, keeping system resources free.

As far as platform-specific improvements, Android users have a few to look forward to, including screen optimizations for both very large and very small Android displays, and the resolution of some lingering text-entry issues.

Mozilla is also taking the opportunity of this Beta release to flaunt the growing library of add-ons for mobile Firefox, now numbering over one hundred.

You can check out both editions of Firefox 4 Beta 4 yourself, available for download now at firefox.com/m.
