Download.com recently published Optimizing Firefox, a special section loaded with tips on how to improve the performance of Firefox. I found a lot of information about Firefox in it that I didn't know. For instance:

• Download performance can be improved by deleting the record of old downloads from the Download Manager.
• Overall browser performance on slow machines can be enhanced using the FireTune plugin.
• Memory usage can be decreased by changing the "Back-Forward cache" value, particularly if your computer has more than 512 Megabytes of RAM.

I'm definitely going to set some time aside to play with my Firefox configuration according to these guidelines. [ via Random Thoughts ]
