cool iris extension for chrome and firefox

I am coming up with another review of my internet experience. This time about a browser extension called "cool iris" which believe me is really COOL. The extension gives us experience of  mac book photosliders on our browser. We have seen how Steve Jobs browse through pictures magically using his fingertips in his keynote addresses. Well this time we can also do it. See the snapshot of the tool

This was the result of a google image search for keralam, which I was able to do on the inbuilt search bar of iris itself. We are able to navigate to multiple page results with just one click and one slight movement on my mousepad. Vertical and horizontal slides enables you to scroll left or right and zoom in or zoom out on individual pictures. I also installed the same extension on firefox. My observation is that it is working better in firefox with better speed and control. The reason might be that the extension has a much longer association with firefox.
Now what are the minuses- so far nothing. Although soon after its installation when I tried to load a few new sites, it took some what longer time. Though I am not sure if the problem is caused by this extension. I googled for effects on browsing speed because of its installation. There was atleast one article that said so, but the comments can be attributed generically to any of the extensions. We know that third party extensions are though incredibly extends the usability, might hamper some basic features such as upstart time, browsing speed etc. Nevertheless through the years we are seeing more innovative extensions with better compatibility. Let me sign off with kudos to all those extension builders out there !

I guess I should also describe about the availability of high speed internet which enables us to try out these extensions, which are data intensive. Well I will do that sometime later. For now happy independance day !
