-They do, but that refers (again) to the CORE. Developers can do whatever they damn well please.
-Citation needed. CustomizeGoogle makes Google ugly. I see no reason why Firefox would do that. And AdBlock is a big deal, but at the same time, it's a bulky implementation and Firefox needs, more than anything, to slim down. Meanwhile, Google and Firefox programmers have similar motives and a similar system to work from. Firefox will copy Chrome, Chrome will get plug-ins, and then it's likely they'll stay as much in tandem as all the big compliant browsers are now.
-Most people don't CARE about profile tracking, first-off. Google, meanwhile, has announced that they'll be making a system for plug-ins, by which we assume they mean extensions, and one of the first ones that always gets made is an AdBlocker. Your Chrome argument is stupid: you can choose NOT to send data to Google if you choose, and if you do then you're totally off the loop. Like Google Toolbar for, what's the name again, Firefox.
Bonus comment:
-I understand that Ashu made a relevant comment that happened to knock yours back, but if somebody argues with you, don't get snipy. It pisses us third-party viewers off. Just argue back with your points and with minimum arrogance, and hopefully people will upvote you if what you're saying is relevant at all. In your case, though, you're arguing a fairly moot case and you're doing it in a pretty factless way, so you'd do best to reassemble your argument if anything.
