burns up too much CPU Rated 1 out of 5 stars

I wrote this review about an earlier version which did not work too well with my "old" single core CPU, and so I gave it a poor review. The new version of this is much better in every way, and it runs well on my systems, which I have upgraded to new dual core uP's and more memory, etc. This is a wonderful product now and I don't know how I will get by without it, or something like it, to fix FF so my eyes don't begin burning, aching, and blurring after only a few minutes of viewing the screen. The new version is worth every effort to keep it up with FF4 and so on. LDH

This add-on is a good idea, and it does work as described. However, when I try it on my XP based Athlon 2GHz 2G Asus MB system, it chews up CPU cycles like crazy. I don't have the greatest computer right now; I suspect if I had a new Core 2 or Quad CPU, more memory and memory speed, it may work better, but for my older machine I can't use it. Between this and Firefox, my computer is at least 5 times slower; browsing the internet, even downloading, becomes so tedious, it isn't worth it. I had to remove this from my system to get the "performance" back up to a usable level.

This review is for a previous version of the add-on (0.3.0).
