I'm curious why you selected Opera instead of Chrome or IE?

>So, I recently dropped FireFox as my main browser and switched to Opera. I didn't use Opera previously because it was a pay-for-browser (or you had to endure banner ads etc.) but now it is free like the others.

>The main reason I switched is because (1) FF is 32 bit (although they have a 64 bit in beta apparently but it reverts to the 32 bit version on upgrades), and (2) it became very sluggish when running on my Windows 7 64 bit computer with multiple tabs. The memory usage went to +/-1 Gb and everything just became crap - poor response, mouse getting stuck, etc. I would then have to close FF and restart it and it would be OK for a while again. And then the cycle repeated itself.

>I installed Opera 64 bit and it runs like a charm. For the same tabs I had in FF the memory usage has now run up to about 2.1 GB and has leveled out at that over the past few days but the response of the browser and computer in general is perfect. I'm impressed.
