On one laptop right-clicking on a tab gives me a Send tab to device option and when I click on it I get a message that the tab was sent. But the tab doesn't arrive on the other laptop. 2. Though I'm using the same version of Firefox on both laptops, I can only find the send tab option on one laptop because the menus are different. And many of the instructions I see online describe items on the menu that just don't show up. I know that I was once -- I don't know how long ago -- able to send a tab from one laptop to another. Most of the instructions are about sending from a phone to a desktop or vice versa. I hope someone can help. Thank you.
