Just downloaded firefox 4 beta 12, at first look i said to my self, "Did Opera not patent the top left smart menu?" you can see the similarity in following images.
Opera has smart menu from very long time and normally they are very good to patent their unique ideas. Couple of other things life they way opera deals with it's plugins, firefox is going that way as well.
I have to say opera is not well supported but it deals with most of the things very well and user experience is much faster than other browsers. I can see in firefox 4 mozzila has improved the performance but still i think opera is much faster browser than firefox. Its not all bad about firefox, i have to say some plugins you get in
firefox are amazing like i love
Firebug.
