I’ve been using Cookie AutoDelete for that purpose for the last few years. It works flawlessly for me and brings me comfort in knowing that I am only being tracked online by my browser fingerprint and IP.
Same, I absolutely love this extension. You can whitelist the websites you use frequently, and for everything else it's like a groundhog day every day.
The cookie banners can be super annoying sometimes, but they are easily removed with uBlock Origin. I also frequently have to solve captchas, but it's not so bad. For example, every time I visit amazon.com to order toilet paper or whatever, it thinks I'm a bot, but at least amazon's captchas are less annoying than some of the others.
Users who do not auto-delete are better served with Consent-O-Matic, this one clicks Deny on all cookie banners and forms by default, but is configurable.
P. S. If I'm using a separate Firefox container just for Amazon, they would isolate my Amazon cookie right? So then I could just whitelist it and avoid capchas?
One thing worth noting: at least when I installed it, the auto clean functionality (the bit that actually removes the cookie/etc data) is disabled by default. This means it needs configuration to actually do anything aside from manual cleaning.
The alternative would be that installing the extension immediately wipes all of your cookies, local storage, and other local data. Most users probably don't want this.
Came here to mention this. This is is probably the most useful extension for preserving privacy while also not breaking things. Sites can store all the cookies they want now, but a few minutes after the tab goes away it's like we never met. Very nice.
