All private windows are in a single container for cookie purposes. If you need more separate containers, you can look at:
Note: those need to be regular windows because private windows are all in 1 container.
If you want to use some Google features anonymously and others logged in, you could consider using containers:
https://addons.mozilla.org/firefox/addon/multi-account-containers/
You can create and name your own containers, so you could create one where you log into Google (allowing its persistent cookies to keep you logged in), and outside of that container, stay logged out.
You can do "profiles" on Firefox too with containers tab, and you can also run multiple profiles at the same time (but it shouldnd't be needed here)
> I was browsing the web and landed upon this website. However, it was able to detect I was using an incognito window and the website https://www.itemonline.com/ was able to detect that I was browsing in an incognito window.
One way that might work is that one or more scripts in the site tries to perform some operations and then assesses the results. I didn't check their script, but imagine that they try to load something that would trigger an ad filter, try to use offline storage, etc. Combining those results may point toward a specific explanation, or the site might give you its best guess.
> I have been a long time user of firefox and can understand that a few loopholes can exist. Can we do something here to ensure that user's privacy is not compromised?
What loophole? How were you "compromised"?
You can't fool all of the sites all of the time. We've become used to consuming their content without having to view their ads, and now some of them are fighting back. Sites are not obligated to give away content for free on your terms. You can walk away if you feel their conduct is unacceptable, you can try different technologies, or you can accommodate them if their content is valuable to you.
(Anti-tracking is not the same as ad blocking, but many of the same servers are involved.)
Containers
If you want to use a site in a tab that looks normal, but with isolation from the rest of your browsing, you could try a site-specific container. Containers don't enable Tracking Protection by default, but since their cookie jar is isolated from the rest of your browsing, that is less of an issue. For ease of use: https://addons.mozilla.org/firefox/addon/multi-account-containers/
Multi-Account Containers if you just want to separate cookies, allowing you for example to be logged in to the same site using two different accounts. You can organize your tabs in separate windows.
Multiple profiles if you want to separate everything, including cookies, bookmarks, history, add-ons, and preferences. You can run multiple profiles simultaneously using the -no-remote command line parameter.
Either way, to open your tabs from last time on start, select "Show your windows and tabs from last time" in the Options/Preferences page (about:preferences), General category.
Enable HTTPS-Only Mode in all windows.
Tags in bookmarks, which makes more sense than using directories.
Firefox mobile with addons support on Android, although limited.
Access to a vast array of settings through about:config
.
uBlock Origin to be unlikely crippled, compared to Chrome-based browsers.
Not that I'm aware of. I'd just bookmark about:profiles
if you're going to be accessing it often. Firefox's containers may be able to replace separate user profiles if you just need multiple profiles for separate online accounts.
In addition, for everyone who uses Firefox:
https://addons.mozilla.org/firefox/addon/multi-account-containers/
It's an add-on made by Mozilla themselves. It lets you create different containers and you can use different accounts/credentials in each container.
Do you need separate profiles to isolate complete browsing history, bookmarks and addons, or to just allow you to login to the same website with multiple accounts? If the latter, you can use Multi-Account Containers addon which isolates cookies and logins for websites while allowing you to use the same profile.
>Is there any way I set specific websites to always open on specific containers?
You can do that via the <em>Firefox Multi-Account Containers</em> extension while on a container tab: Context menu -> Firefox Multi-Account Containers -> [X] Always Open in This Container
You could use the <em>Firefox Multi-Account Containers</em> extension to open each account in its own container, then switch between those container tabs. For Reddit specifically: You can apparently switch accounts on the fly with <em>RES</em>.
> I use Vivaldi for my personal FaceBook and personal google & YT accounts. Then my Outlook Microsoft, Reddit, Ebay, and Amazon go through Opera.
Just so you know, you can use containers for this: https://addons.mozilla.org/firefox/addon/multi-account-containers/
hi, you could try https://addons.mozilla.org/firefox/addon/multi-account-containers/ - this won't rename the tabs but it will color-code them so you can easily recognize and keep the accounts separate.
How many regular and how many private windows do you have open in your session? All regular windows share a saved-to-disk cookie jar, and all open private windows share an in-memory-only cookie jar. If you need to slice and dice more finely, take a look at Containers. This extension facilitates: https://addons.mozilla.org/firefox/addon/multi-account-containers/
