PickBrowser
PickBrowser is a program that lets you pick the browser you want to open external links.
If you have more than one browser installed on your computer, you probably have been annoyed that there is no easy way to select which browser opens external links—such as links in e-mail messages. For example, Firefox may be your default browser, but you may have an e-mail link that you want to open in Internet Explorer. This is a common scenario in corporate settings, where links to an intranet are typically opened in Internet Explorer, for purposes of authentication.
PickBrowser neatly solves these problems by letting you pick the browser you want when you open an external link. Clicking an external link opens the PickBrowser window, from which you can select the browser of your choice. PickBrowser works by becoming your “default browser”. Settings are enabled at your option and are completely reversible. Aside from handling external links, your browser experience remains unchanged.
In addition to operating interactively, browser selection can also be automated through Domain Filtering and AutoPick. Domain Filtering lets you target a browser to open links to a specific domain. AutoPick allows you to route all links to a specific browser.
