I love Firefox. I really do. It has its issues, just like your iPhone or laptop. But you love your iPhone despite its issues. But then again, your iPhone doesnt eat up 600mb of memory to show you 6 websites. Which firefox does, or used to do shall I say. After I installed the beta release of FF3, the first thing I noticed was that the memory hog issues were -gone-.
Check out techlahore’s screenshot of the current version of FF

See that? With FF3, no longer. The beta has other issues (like those you find on a new suzuki..buttons falling off and the sort) , so download at your own risk. But it will fix the memory hogging problem!
I suggest people look for enigma browser and download it from http://store.democratz.org
You can find the link just above the products and you can download it for free.
Engima runs faster than Firefox and you can easily run 32 tabs and not slow down the machine.
