Looks like the cookie banner blocker, originally scheduled for Firefox 114, didn’t make it into today’s Firefox 115 either. Brave and DuckDuckGo already block cookie banners.
For Firefox, we need to rely on uBlock Origin. Unfortunately, there’s no uBlock Origin for Firefox on iOS.
Whats the cookie banner blocker?
An upcoming Firefox feature that automatically rejects or accepts cookie banners for the user on as many websites as possible.
