If you use Firefox
I highly recomend the extension Faster Fox.
If you have broadband, and even if you do not, it makes Firefox much faster to initially load and pages and pics seem to appear faster as well.
It was the best extension I have found yet, other than Bug Me Not, and it has gone downhill as the knews outlets spam their server.
I figured that since half my readers use Firefox, I ought to share the goodies I find.
Feel free to add your own recommendations.
