Casting your Firefox browser to a Google Chromecast allows you to view web content on a bigger screen. Unlike the Chrome browser, the Firefox browser doesn’t have a built-in Cast icon. You need to download a plugin to get cast support.
Alternatively, you can use Chrome browser to screen mirror the Firefox browser from your PC. Similarly, smartphone users need to screen mirror the entire device to cast the Firefox browser.
Note – The following procedure is applicable to TVs with built-in Chromecast support or Chromecast-connected TVs. Just ensure that devices are connected to the same network.
