Current Firefox version (2.0.x) consumes too much memory (even when it’s being idle). Several improvements have been designed to reduce this memory usage and it will be available when Firefox 3.0 shipped. Still Firefox 3.0 RC2 eats-up lot of memory.

Meanwhile, for you who wanted to optimize Firefox’s performance, you can try this tools : Firefox Ultimate Optimizer. It’s a tool which can work silently to reduce Firefox’s memory usage, thus frees your system with heavy memory loads. With this tool Firefox RC2 in my system is just using ~3-4MB and maxmimum ~10MB with lot of tabs open. This tool really healed my system, otherwise Firefox used to eat more than 30% of system memory. It is available for Windown only and requires .NET Framework 2.0 installed. It will run in your system tray and work in background. Pretty nice tool.

Even though most Twitter users use it to inform the world of their bowel movements, Justin Wickett came up with a slightly more clever use for the app. He uses an INSTEON switch and a computer in order to monitor a Twitter account for the on or off switch command send from his cellphone. When it’s received, the computer flicks the switch and turns off the light. Between the text message delay, the fact that he needs a COMPUTER hooked up, and the general way-too-geekiness of Twitter, he’s better off setting up an actual home automation system for his lights.
