How many browser windows do you usually keep open?
Here's a screnshot of my web browser right now. It's a little excessive because I have been looking up some info on something. Usually I have about 30 open.
And here's the reason I like Opera much better than Firefox:
In Firefox it would have been AT LEAST 1.5 GB.
At least. Firefox is a memory hog and does not release the memory when you close tabs/other opened windows.
They need to fix dat shit.
