Hi there, It sounds to me like you needed to have closed Firefox first, as it restores tabs from the previous session if you unintentionally forced close the browser. Have you tried "syncing" them in your browser? Also, if that does not help, then please check out the following two links that I'm listing below. They may have an answer, but I cannot guarantee it. https://support.mozilla.org/en-US/kb/send-tab-firefox-desktop-other-devices https://www.reddit.com/r/firefox/comments/bj8e12/send_tab_to_device_is_not_working_properly/ I do hope that you find a solution. Good luck!
