I click the star. Tor Browser doesn't have cloud sync but that's a small price to pay to prevent stalking. If I'm on my pc looking for something and realize it was saved on my phone I just have to take it out of my pocket, unlock it, open the browser on there, then i can see it.
Sure that sounds like a lot but it's the same as taking a foot step. There are a lot of steps but it's actually just all automatic and takes 1 second.
