The recent Chrome Beta for Android update was notable for including password and form sync, but it turns out there is another feature lurking beneath the surface, and it's potentially a big deal. Google has built in a data compression proxy for Chrome that can reduce bandwidth usage by up to 50% on mobile networks. You'll have to do a little digging through the Chrome flags, but it's relatively easy to switch to the fast lane.
The perennial favorite of Firefox and Chrome power users has arrived. Adblock Plus for Android was just released to the Google Play Store, compatible with all devices running 2.1 or higher. Just like its desktop counterparts, it'll block ads in your browser... but only in certain circumstances. Those who are rooted (regardless of Android version) will block all ads in the standard browser and Chrome. If you're not rooted, it'll block ads on WiFi for Android 3.1 or later.
