I have a fireTV and am looking to send a firefox tab from my computer to the television. i have logged into both, however, when i click the three dots on the computer's browers to 'send to another device' as suggested in articles, that does not show up. there is a 'share' button but that is a microsoft link that wants me to share to other bluetooth devices. any help is greatly appreciated. about to just chromecast it to the TV at this point
