Reducing Firefox RAM Usage

(via Digg)

One Federico Mena Quintero showed a proof-of-concept on how to reduce memory consumption of Mozilla Firefox on your PC.

When you run Mozilla or Firefox and load a web page with images, it stores the uncompressed images as pixmaps in the X server. In particular, it seems to maintain live pixmaps for all the images in all the tabs that you have open; even if a tab is not visible, the images will be in your X server’s memory.

When you exit Firefox, the X server is smart enough to return this memory to the kernel.

Web pages use compressed images, of course, to reduce download time. These images will likely take up a lot of space when uncompressed.
