Although Firefox does not directly support the ActiveX plugin used by many business and customer management applications, you can circumvent this limitation by installing the IE Tab extension. This extension lets you open a website in a separate Firefox tab using the Internet Explorer rendering engine, thus allowing you to run ActiveX controls.

Click the Firefox menu button and select "Add-ons."

Type "IE Tab" in the search box and press "Enter."

Click "Install" and then restart Firefox to finish installation.

Click the "IETab" button to open a new tab using Internet Explorer. Alternatively, right-click on a link and select "View Page in IE Tab."
