Firefox totally sucks when it comes to memory usage. After couple of hours of heavy browsing, the web browser starts to consume half of your system’s memory. The only way to fix this is to restart your browser, but that can be really painful if you have some important tabs and you don’t want to close them.
Mozilla claims that this is actually a feature, not a bug. Firefox caches pages, images and other elements, so that it can render the page as fast as possible. Consuming insane quantity of memory for performance isn’t favorable to anyone. Mozilla has realized the situation and have decided to take up memory problems as a priority, especially when they are trying to cram the Firefox browser into mobile platform.
Over the next few months, you can expect developers work a bit more aggressively over the memory issue. You might possibly see the difference in the upcoming version of Firefox 3. CyberNet wrote about an interesting plugin called RAMBack, which will empty useless cache and save memory.
