I might be the only one but I'm quite annoyed that Safari's incognito mode works like this. I WANT it to have knowledge of all the other incognito tabs of the same window. Only when I make a new incognito window, it should be a new container.

Pretty interesting how preferences can vary, because this bothers me everytime I use incognito mode on safari and think, can this not just work like in Firefox.

In the old days logging in twice would bother me as is have to type in a password, but now with password manager and fingerprint/face scan it's low effort.

It's very handy for sites where you may have more than account

For that Firefox's container tabs are a much handier option as you can stay logged in and also open new tabs that are already logged in. It has colours to tell apart which tab is part of which container

On desktop OSes, I definitely also prefer that behavior. I wonder if Safari behaves like that for consistency with iOS, where there isn't any hierarchy above tabs, so it would be a choice between no separation at all or sandboxing each tab individually?

> The comment was: make the Firefox containers work in private mode.

My solution to this is having multiple Firefox profiles where the default one clears all history/cache/etc automatically upon closing (default in Librewolf). It's not technically private mode so containers work.

temporary containers [0]

> disposable containers which isolate the data websites store (cookies, storage, and more) from each other

Granted, they're not in private broswing mode just normal mode, but same effect

Yes, that's the one I want fixing, and possibly moving from extension to feature.

Why would you create a privacy tool, and then not offer it in private mode. Makes no sense.

(You can setup Firefox so it's permanently in Private Mode and clears history and data on exit - as per Libre comment above -,which is how I have it set)

I actually prefer it the way it is now. For me, private mode is effectively an extra temporary profile that is full featured, but wiped once the last window is closed. I usually don't need more than one.

But I understand that other people have other needs. It can be very useful for developers for instance. Make it an option, maybe.

A "private tab" feature in addition to "private window" could be a useful, if potentially confusing

If you're on desktop, the "temporary containers" extension does this.

I see both. I wouldn't want every tab to be separate but I occasionally want to have more than one independent private profile at a time. It would be nice if I could do this. Any sort of ephemeral container tabs option would probably satisfy this option and could maybe even remove most of my use of private browsing if I could just open ephemeral containers in an otherwise regular window.

How about per-window private sessions?

That would be limiting if I can't have multiple windows of one private session. (Although admittedly this is something I do quite rarely)

     firefox --profile $(mktemp -d) --private-window

or wrap it to delete the temp dir after firefor process exits.

Unfortunately it doesn't work like a separate profile for extensions so you can either enable them and trust that the extension doesn't leak data from private windows into your main profile or you can disable the extension - there is no option to enable the extension but enforce that the extension sticks to the private profile (with possible exceptions for extension settings which should persist).

Shameless, deprecated plug: I built a very hackish Firefox extension to do that about 17 years ago [1].

I still feel that the isolation is backwards. Instead of having me to split containers, ask me to merge things like google.com and youtube.com, but by default keep every domain isolated.

They have to ask for sign ups, otherwise they'd get blasted by bots spewing whatever.
