How to make Opera consume less memory | Opera memory hog gone

I love Opera..Its fast , its efficient, and web experts will agree with me that its the fastesthow to make Opera consume less memory | Opera memory hog gone browser to surf the internet. Screw Internet explorer, i hate that , safari is too buggy and Firefox , though is good, but has its fair share of memory leaks problems which tend to increase with each new version. Yep..I tried Firefox 4, but as it turns out, it was too heavy for my taste and a lot of installed extensions were not supported, period. The response time increased as I opened a lot of tabs in it and hence, I finally decided to turn on to Opera 11.

I installed it in a jiffy and there we go. Smoother browsing experience and increased productivity :D but then I opened task manager and checked out the memory usage.
