Using more than one browser at once is not just the practice of web designers, everyone can reap the benefit of having multiple browser open, instead of multiple tabs or windows of the same browser. You can separate different types of pages more easily, you can keep your workflow in a different space than your personal like, and you can better use the different advantages of different browser.

If you work on the web and/or live an active social life here, you surely have a lot of “accounting” type pages open, or pages you want to monitor regularly. I call my email accounts and adsense account “accoutning” pages, since these are in no way part of my workflow, separating them is a big productivity booster. Firstly, if I take all of these pages and open them in Chrome instead of Firefox, I will be left with a clean environment to work with in Firefox, and quite possibly, less memory usage. Once you have these separated, the less clutter will help you focus, and you can also put one browser on a side monitor, and your main one right in front of you, if you have a dual monitor setup.

You can also reap the benefits of different features if you use more than one browser. I wouldn’t really use Flock for working, but its a great browser for living your social life, so using Twitter, Facebook and such is much easier and faster. If you are more productive in your personal space, it will leave you more time to work, or simply more time to relax.
