Mozilla is working on a feature to automatically reject cookie prompts in Firefox, aiming to reduce the annoyance of numerous cookie dialogs on websites. The feature, called Cookie Banner Reduction, can be enabled in the Firefox Nightly version and will select the 'reject all' option if available. This move is in response to regulations like the GDPR, which require websites to obtain user consent for placing cookies. The feature is not yet available in the stable version of Firefox.
