Is there a way to have Firefox browser in the quick launch at the bottom right side of screen, like Netscapre does? My PC is very slow , so faster it opens the better.

Yes, you can easily put the Firefox icon in the quick launch area in the lower left part of the task bar which is where I think you really want it anyway.

Simply click on the Firefox icon on your desktop or in the "Progams" menu and drag and drop it to the quick launch location on the lower left of the taskbar right next to the "Start" button and then release. Now you have a Firefox quick launch ready to go!
