A place to discuss the news and latest developments on the open-source browser Firefox

All the incognito browser windows share the same "session" in Firefox. So say you open an Incognito window to browse Facebook or something, then you open another Incognito window, this new incognito window is linked to the previous incognito window, meaning you are logged into Facebook at that new Incognito window as well. This is because, as I explained before, all the incognito windows share the same "session"

The only way to clear incognito window is to close ALL of them and then create a new incognito window. You dont have to close the main non incognito Firefox window though, just close all the incognito windows. Then open a new one, now your previous session is destroyed and you are new again.

You may know it but its not that common knowledge as it should have been

Maybe it's because I have a programmer mentality but this is exactly the behavior I would expect, otherwise the "open link in new window"won't work reliably, all popups would fail and you couldn't "tear" off a tab in a new window

[–] cy_narrator@discuss.tchncs.de 1 points 1 year ago

You are someone who knows how Browsers work so you think this way.

[–] rbn@feddit.ch 41 points 1 year ago (1 children)

For me that behavior was expected. E.g. if I open a link from incognito in a new window, then it obviously should also use incognito but share its context with the previous sessions, otherwise it would require you to login over and over again. If an independently opened incognito window behaved different from a link-click window, I'd find it even more confusing.

[–] RogueBanana@lemmy.zip 12 points 1 year ago (2 children)

I would say it should be the opposite. Separate windows should be independent but tabs on other hand can share same session.

[–] DogMuffins@discuss.tchncs.de 3 points 1 year ago

Nah, what if you drag a tab from one window to another.

I use containers for everything. Best thing Mozilla has ever done.

[–] moonmeow@lemmy.ml 35 points 1 year ago

seems counter intuitive.. each incognito window should be separated into their containers.

seems like a good idea to take that container addon and apply that to incognito.

IDK how else it could work.

Anyone who understands what a private window actually does, would expect it to work this way.

[–] heavyboots@lemmy.ml 29 points 1 year ago

I think what you are looking for is Containers. FF uses containers to wall things off from each other, whereas Private sessions are still all sandboxed together, as you discovered. I know this is quite different from how Safari, for example, handles things, but you can accomplish the same things, just a little differently.

[–] Truck_kun 21 points 1 year ago (2 children)

... Are there people out there expecting more than a private/incognito session not saving your session data when you end it?

That is the sole reason I use private mode, because I don't want it to save cookies/cached/temp files/history locally for whatever I'm visiting.

[–] miss_brainfart@lemmy.ml 3 points 1 year ago

I mean, the naming is a bit misleading, to be fair. Or at least not specific enough. Many people don't actually know what or who it makes you private towards.

Which is why I appreciate browsers having a little notice about common misconceptions when opening a new private tab or window.

[–] JohnEdwa@sopuli.xyz 2 points 1 year ago (1 children)

Btw, a good addon for doing that all the time is Cookie AutoDelete. Building up the whitelist will take a while, but it's worth it in the end.

[–] Truck_kun 2 points 1 year ago

Thanks for the recommendation.

I believe it adds some features above Firefox's defaults, but for anyone reading that doesn't know, Firefox does have a feature

"Delete cookies and site data when Firefox is closed." under "Privacy and Security" in settings -> under the "Cookies and Site Data" sub-section.

They also have a "Manage Exceptions" button to build a whitelist and blocklist of websites to always allow cookies and site data, or always block cookies and site data.

For those looking for more extreme add-ons are a great idea, but always prefer built-ins when available/sufficient.

I'm fine with just using Private browsing in my case. My wife knows I look at porn, but I don't want it to be in her face if she ever uses my computer.

[–] observantTrapezium@lemmy.ca 14 points 1 year ago

It's not even called incognito in FF.

[–] JokeDeity@lemm.ee 12 points 1 year ago

That's not that worrying to me.

[–] detalferous@lemm.ee 8 points 1 year ago

This is so counterintuitive and so important. Thank you.

[–] stolid_agnostic@lemmy.ml 5 points 1 year ago (1 children)

For reference, private mode in Safari protects you from this.

[–] potustheplant@feddit.nl 12 points 1 year ago

"protects" you from this? Honestly, this is exactly how I'd expect incognito mode to work.

[–] fmstrat@lemmy.nowsci.com 4 points 1 year ago

Use profiles instead of incognito when possible. You can have profiles, with different privacy settings, for anything.

[–] notenoughbutter@lemmy.ml 3 points 1 year ago (1 children)
[–] joyjoy@lemm.ee 2 points 1 year ago

firefox profiles have a bad UX in my experience. The Multi-Account Containers addon works better. There's also Facebook Container, which uses the multi-account containers addon.

[–] possiblylinux127@lemmy.zip 2 points 1 year ago (1 children)

If you want security use Tor

[–] cy_narrator@discuss.tchncs.de 4 points 1 year ago (1 children)

Tor is for like the EXTREME end of security that may not be required for casual users but Tor has its place in my computer

[–] Forcen@lemmy.one 1 points 1 year ago (1 children)

This might be a better suggestion then: https://mullvad.net/en/browser

Useful even without a VPN.

[–] Aatube@kbin.social 1 points 1 year ago (1 children)

How is it better than, say, LibreWolf or Waterfox?

[–] Forcen@lemmy.one 2 points 1 year ago (1 children)

It's the Tor browser without Tor, there's a wipe button just for this issue.

[–] Aatube@kbin.social 1 points 1 year ago (1 children)

I'm asking for like specific features

[–] Forcen@lemmy.one 1 points 1 year ago* (last edited 1 year ago) (1 children)

It's not a replacement for Firefox or it's forks, it's a complement to your main browser. It's like private browsing but always private and always separate from your other browsers and won't save any data locally except maybe bookmarks.

The link I originally posted should explain this but here is a page that explains it in greater detail: https://mullvad.net/en/browser/hard-facts. Some more links:

[–] Aatube@kbin.social 1 points 1 year ago* (last edited 1 year ago) (1 children)

It is a fork of Firefox and what I'm asking is what advantages it gives over librewolf, which also tries to do the same stuff

Your last link is a 404

[–] Forcen@lemmy.one 1 points 1 year ago

Mullvad is a fork of Tor Browser so it gets some features from that like:

Yeah, I also found out when I was manually testing our product's logged-out UX at work and the 2nd trial started logged in.
