Google Chrome has become as bad as IE in terms of hidden settings, or settings that are just not there. In Opera and Firefox, I have no issues accessing numerous networks. I can change network settings on the fly and have different settings for different browsers. With Chrome and IE I need a new browser installation everywhere, because Chrome either uses no settings or IE settings. Being able to set proxies and network settings in an add on browser is an important feature for testing.
IE at least has proxy support that works. Chrome is singularly terrible in this respect. Try using a proxy script with a file URL, pointing to an authenticated proxy and move between networks without closing the browser (Chrome now keeps a process running in the background even if you closed all your Windows, so difficult to avoid), and you'll see what I mean.
