Why have more than one browser?

I have 4 browsers on my Mac: Safari, Firefox, Google Chrome and Camino.

Many people don’t know that you can have more than one browser open at the same time. For instance, I have several Gmail accounts. To avoid having to sign out of one and sign into another account on the same browser, I access each Gmail account on a different browser.

Once, I helped a friend sell an item on eBay, working with her eBay account on the browser Camino, to keep the transaction separate from my own eBay account.

The only limitation of how many browser you can use at the same time is memory, which with current Macs is not an issue.
