Comment Re: Firefox vs. Opera (Score 1) 211
Firefox (and Chrome, and IE, and Safari) copied pretty much everything from Opera.
This is just wrong. By now, each browser has copied a lot of features from the others, but all of the major browsers had a "killer feature" that caused a lot of people to switch and allowed it to gain traction.
Firefox: very lightweight, excellent extension support
Opera: rendering speed, some advanced features
Chrome: stability (separate process for each tab, plugin), JavaScript speed
IE, Safari: come preinstalled with the OS, well integrated
Note that none of this is unique to the particular browser anymore, and some of those don't even apply anymore.
