Which better? I means the lesser memory consumption.
By the way, in my Ubuntu 12.04:
When I clicked Firefox (FF)'s Icon, Firefox's window will show-up.
And if I download a file, a download's window will show-up.
But if I minimize the FF's window, I unable to maximize back again by clicking FF's Icon.
I'd tried to minimize the download's window in order for having my FF's window back. But it cannot. The window, which will be show up when I click the FF's Icon is download's window only.
So, I choose a file, which downloaded => right-click => go to Download page.
And the FF's window will show up again.
Is this normal?
If not, how can it be fixed?
