That honestly sounds like a you issue, not a browser issue.
I would have killed for the capabilities web browsers have now back in 2000. I was forced to build Java applets to get anything close, and the user experience sucked.
Websites today offer little over the ones from 15-20 years ago functionality-wise. In fact they have less features in the name of 'simplicity' that results in their being bloated memory hogs with javascript.
