Use a vpn with a Eu server. More sites like google will show a cookie popup with the “reject all cookies” option.
Reject all cookies if it exists. Otherwise accept cookies and then click on the :
shield icon > cookies and site data > delete (trash icon)
This is super useful when you want to read an article on some news website and it shows a cookie popup.


There are so few sites that should leave a cookie I just set it to purge everything on browser close, and then make exceptions for the ones who actually should leave a cookie.
Pretty sure every browser now has the option to dump all the data when it closes.
I would do that but I want to stay logged in on some websites like lichess.
The login scene is so terrible nowadays with 2fa, passkeys etc. It’s not as easy as just remembering a password or using a simple password manager.
Just whitelist the ones you want to keep. Pretty sure Firefox now let’s you whitelist, I use a plug in because I’ve been doing it that way for years (ie before ff had the option)

Deleting cookies on close? I had my Firefox set up to do that about 20 years ago

I assumed you meant the whitelisting not the autodelete - cookie autodelete on close has been in FF for years, but some time recently they brought in whitelisting as well - go to settings, privacy and security, cookies and site data, manage exceptions
Might be worth deleting CAD and use the inbuilt option to reduce canvas fingerprinting
Pretty sure i saw it the other day and yeah me too on CAD
Use two browsers. One for logins, the other dumps all data on close.
same I use IronFox for random stuff and Brave for website that actually requires a login
Look for ‘manage exceptions’ in the settings if your browser is Firefox-based.
Librewolf does that by default, among other things. And as thanksforallthefish mentioned, in settings you can whitelist some pages to prevent cookie deletion, if you want to remain logged in.
