I wish that I can open all the tabs I have open in Firefox in Google Chrome, with the click of a button. Or for that matter from Internet Explorer to Firefox, IE to Chrome, and all permutations.
Chrome is more powerful in certain ways, and if I’m watching a lot of videos and listening to streaming radio during a web session, I want to be able to open all tabs in Chrome. I think Chrome does a better job of handling large, memory-heavy web apps. Each tab in Chrome is considered a new browser window, in a way – memory usage on individual tabs does not bleed into other tabs.
As a user, I should be able to choose which browser I want to view a web page in, at any moment in time.
