Friend, do I understand that you're mad that private windows don't allow the system to introspect what content you're viewing in a private window?
BTW, in the spirit of being helpful: if you're using private windows just for 'fresh session' behavior, Firefox offers two other knobs for that outcome: Profiles and Containers. In Chrome I'm with you that Incognito can be a very cheap way to login to a site multiple times, but in FF you have more choices about that problem
I am, yes. It worked as I described up until I think October of last year.
I’m logging in and out of client accounts - often for services that don’t do delegate access - so private windows work nice for me to make sure that I’m always cleared out of what I was working on before changing to a different project. Often I copy things in private windows that aren’t secrets, it just happens to be how I used the feature.
Containers and Profile are great - but - I’m not trying to have 50+ of them at work, much easier to flip open a private window.
I acknowledge my usecase is unusual and for most I think the feature makes sense - I just want to be able to turn it off, an about:config would be fine.
I have a very useful plugin that automatically deletes website data (other than history and downloads) after a configured interval once you’ve closed the tab or window. You can define an exception list. I cannot recall its name, I’ll post back when I’m back at my computer.
