Yes it is!
Running Adobe hotoshop, Lightoom.. Flash Professional.. Illustrator, and Dreamweaver and an whole slew of browsers can be a tad taxing,.
FR makes it easy to open one after another tab...and I just never seem to get around to closing them...in time..
Well, yeah. FR is mostly text; I've visited FR using Internet Explorer 4 (mostly when working on my x86 micro-controller designs, for which I am targeting Win3.1/WinNT 3.51 on the 80386EX)
I generally open 7-10 tabs at a time as I go through the posts. Haven't had problems with Chrome getting the hiccups with it though.
Running Win7 Prof with 8GB RAM and also usually have about 50 tunes queued up in WinAmp (using older version 5.581 after years of vers 2.81 because of simplicity and utility).
