I have a new laptop and my DH has taken custody of my old one. I can't find a way of stopping sites like Mumsnet and MSE popping up on the front page of the Firefox browser as a tile for him to click on, and when he does the log-in box is pre-filled with my username and password.
Now this doesn't matter in the grand scheme of things, he's not particularly nosey and I've got nothing to hide except maybe a few threads on MN where I've moaned about him but it is irritating him. He is not tech-minded, I'm better at it than he is, but no expert either so what do I do to remove old passwords and log-ins that are stored? We don't want to reformat the laptop as there's lots of stuff on there that he finds useful.
Thanks for any help and advice
