ActiveX is a technology specifically created by Microsoft for Internet Explorer. ActiveX "controls" allow Internet Explorer to access embedded multimedia content in web pages (such as "Flash" video streams). Mozilla's Firefox does not support Microsoft's ActiveX technology for many reasons, but mainly because ActiveX technology has made Window's operating systems a severe target for malicious software. In other words, you cannot run a Microsoft remote desktop ActiveX control in Firefox. Instead, Firefox supports "plugins" (also called "add-ons") and "extensions," which function like ActiveX controls that allow you to view and use embedded multimedia content within web pages.

Visit Mozilla's "Add-ons for Firefox" web page. Select an add-on (plugin) you would like to download and click on the "Download Now" button. Follow the simple installation instructions, Firefox will restart and will automatically use the new add-on to view embedded multimedia web content. Alternatively, when visiting a website that requires an add-on Firefox will ask you if you would like to download and install it, automatically; click the "Install" button at the top of the web page, when prompted, to download and install the plugin.
Disable plugins you no longer want by opening Firefox, clicking on "Tools," located at the top of your screen, and selecting "Add-ons." Select the "Plugins" section on the top right corner of the "Add-ons" window. Select the plugin and clicking the "Disable" button.
Update plugins by opening the "Addons" window (see step 2), selecting the "Plugins" section located in the top right corner, and clicking on the "Find Updates" button located in the bottom left corner. Upon clicking "Find Updates," Mozilla's "Plugin Check" web page will open, lists all of your current plugins and tells you which are up-to-date and which to update. Click on the "Update" button to update out of date plugins.
Tips and warnings
- The general rule of thumb when downloading add-ons or plugins is, if it's not necessary to the function of your computer then don't download it. Plugins are made by third-party organisations and can contain malicious software. Only download plugins that Mozilla approves on there website to keep absolutely safe.
- Frequently update your plugins to ensure maximum performance.
