BrowserSwitch enables you to open the clicked URL in different browsers depending on the domain of the URL.
Use case:
If your company's system only supports Internet Explore (IE), you can use IE for your company's system and open other sites with your favorite browser.
Note:
Clicking on a link in a browser will open it in that browser; BrowserSwitch is only used to open the browser from other software (Outlook, Excel, etc.). Recently, some internal pages are not fully IE-compatible due to Office 365 Sharepoint server, but unfortunately, clicking on a link to such a page in IE will not open it in another browser.
