My 2017 Macbook Air died, but I have Time Machine backup, which I haven't yet accessed. I bought a refurbished 2020 Macbook Air, and I put a current version of Firefox on it, basically to test out the computer. I want to retrieve my old bookmarks, which should be on the backup, but I've seen different and confusing procedures on how to do this. Should I remove the new Firefox before I use Time Machine? Can someone give me a good way to get these bookmarks back? Thank you, James
