How do I use the Test IE Firefox add-on?

Download and install the Test IE plug-in from Integrations. Enable the Add-on bar (Mac: Cmd + /, Win: Ctrl + /) and click on the BrowserStack logo to open the panel. Select the Internet Explorer version, and the current page opens within a BrowserStack session, in a new tab.

Note: You have to log into or create a new BrowserStack account to test the webpage.
