This possible in Firefox?

Is it possible to have content aware resize...so when I press the maximize button, it open increases the size to the maximum size it needs (like safari does)?

Have a look at New Tab King. I used it a while ago and I seem to remember that it does some of the things you mentioned. Not sure on everything though.

Sorted that issue, just after the content aware maximize now

Thanks.
