To be honest I never thought of that and this looks like exactly what I need. Do you know if it works with subdomains, so if I add example.com to exceptions will it also store cookies from subdomain.example.com ? However I’m not sure if cookies are being stored by a subdomain or the main domain for some sites, for example there are sites that host user’s blog at user.website.com .

Also I wish there was a button in address bar or somewhere else to simply click and “Add an exception to allow storing cache and cookies”.

UPD: Press Alt, go to Tools -> Page info (or press Ctril+I) -> Permissions, there is a button to Allow Set Cookies there.

Thank you very much, I never noticed such a setting!

Can you tell me more about where do I disable cookies and add exceptions for sites which I do want to store cookies? Does this also remove data other than cookeis (cache, local storage etc.)?

Can you please link me to a guide or something, how do I configure firefox to use containers automatically? I guess I want two containers, for the sites I trust just one “regular” container and open everything else (except a few whitelisted sites) in a “throwaway” container that I can remove and create again to get rid of all local data. How do I “whitelist” a few sites to open in container 1 and configure firefox to open everything else in container 2?

UPD: https://github.com/mozilla/multi-account-containers/issues/462

So 8 years passed and still no possibility to set default container for Ctrl + T or “+” on tab bar in UI…

And why don’t you configure your Browser so that all data and caches are deleted when you close the browser?

Doesn’t it also close all tabs on close and remove all history? Can I add exceptions to this? So that tabs stay the same after a restart, and few sites (like mastodon) keep their cookies, but everything that is not whitelisted gets the data cleaned.

No, I’m not looking for Tor.

Thank you. Maybe there’s some extension to quickly destroy site data (cache, local storage, cookies, history entries) when closing tabs? Like a second button next to “close tab” that says “destroy site data and close tab”.

Basically I want each tab to be unable to track me on other tabs, so tab isolation. Does firefox to this in normal containers?
