I use multiple profiles. Got both personal and work ones for both me and the wife, close the windows when they’re not active, and they are set to keep track of the tabs. But keeping them open? Hell no. And I’m retired now. It’s been six months since I’ve used the work profile.
If you want to do profiles (in Firefox), add -p to the shortcut’s target line, at least in windows. I think. It’s been a while since I set it up. It’s -p somewhere
