Well, I have a habit of opening like ten to fifteen tabs at one go, and yes, it sometimes does lag. Maybe my laptop is too old (it's three years old) but when I do the same with Firefox, it's worse.
Things get worse especially if I open sites like The Star Online, where they have plenty of flash and other resource-eating applications.
As for the site not found page, I think I'm annoyed because I see that page more often with Google Chrome than I do with Firefox. I don't know, maybe my Celcom broadband doesn't agree much with Chrome?
In any case, Chrome and Firefox are still far better than Apple Safari, in my opinion. Safari has a very beautiful interface and looks very futuristic, I must admit, but gosh! My computer froze the moment I attempted to run Safari.
As of date, I've used the following browsers:
1. Internet Explorer
2. Netscape Communicator/Netscape Navigator
3. Mozilla Firefox
5. Google Chrome
Web browsers have certainly come a long way, haven't they?
