How does uBlock Origin help here, though?
I don't think it blocks Cookie banners?

It can hide the popup but all the rapist advertising companies take that as yes because you didn't say no.
Use consent-o-matic to automatically opt out.
Doesn't matter if I opt in or out if I just delete them all on closing the browser and they all disappear.
Firefox can be set to delete them when the browser closes without plugins
Don't do that.
Cookie extensions
❗️Sanitizing in-session is a false sense of privacy. They do nothing for IP tracking. Even Tor Browser does not sanitize in-session e.g. when you request a new circuit. A new ID requires both full sanitizing and a new IP. The same applies to Firefox
❗️Cookie extensions can lack APIs or implementation of them to properly sanitize: e.g.

As of Firefox 86, strict mode is not supported at this time due to missing APIs to handle the Total Cookie Protection [... followed by instructions]
I don't get it. Of course it doesn't help with IP tracking of fingerprinting, but it deletes all cookies when I leave a site. My browsers runs very long on desktop and mobile, so Firefox's 'Delete cookies on close' doesn't help much.
"don't lock your door, it does not prevent scammers from getting your home address"
???
yeah, we know deleting cookies doesn't prevent IP tracking, that's also why I use a VPN
Is that needed if ublock already stops all the tracking scripts from loading?
Yes. Because cookies are used for tracking and can be set without the aid of Javascript.
For anyone interested, cookies pre-date Javascript and are baked in the HTTP protocol by way of a Set-Cookie header that the browser responds to by storing whatever information accompanies the Set-Cookie header; usually a unique id that can then be used to track what pages on a domain you visit.
uMatrix once again to the rescue. It can block cookies. The only downside to uMatrix is that it dis-/allows based on su domain, so you can't accept a log-in cookie and reject the tracking cookie, if they are served by the same subdomain.
uMatrix is unmaintained since 2021, that's another downside

It does, just need to enable the filter list for it. It'll block most annoying things on top of the usual ads.
By default it does nothing about the banners, but blocks most tracking cookies. With some config, it can both enforce a comprehensive cookie policy you set, and hide the banners for you.
It does, if you choose so. Settings -> filter lists -> cookie notices -> easylist/ubo cookie notices + adguard/ubo cookie notices
Thanks a lot!
Just activated it, and a short test on two of the news sites I visit regularly confirmed it to be working! :-)
It helps partially. As it will block known trackers and tracking cookies.
I use Cookie Autodelete. Doesn't matter what I choose, it's getting nuked when I close the tab. Handy to clear out IndexedDB and localStorage too, for sites that only let you read one or two pages before putting up a paywall.
What's the benefit of an extension over setting Firefox to autodelete and setting exceptions in the settings?
CAD deletes cookies for sites as soon as I close the last tab from that domain, not just when quitting the browser.
Especially on android the settings to delete stuff on quit is pretty useless, because I never quit Firefox through the menu, I just remove it from the recent apps, which doesn't trigger that stuff.
Oh gotcha, I'll have to try it out then, thanks!
You can probably rig up something similar using firefox settings depending on what your needs are for convenience and granularity.
I just meant was there a benefit to choosing an extension over Firefox's settings
Does it allow you to select the ones to keep? I'd like to delete everything, but signing into the services every day is annoying as hell, so I'd appreciate a solution to keep the authentication ones.
Yeah, you can manually whitelist domains (including expressions). I do this for sites where I don't mind keeping cookies around (like lemmy).
yup. this.
I'm gonna copy-paste my comment here. Please, don't install such extensions.

No one said deleting cookies prevents IP tracking. Deleting cookies prevents cookie tracking.
I'd recommend the Consent-o-Matic extension which works well, even on mobile.
Love it when sites flip the language or the decline buttons to try and trick you into accepting everything.
