Possible to automatically reject cookie banner in Firefox without using any extension?
yes, from v120 it is possible. Go to about:config and set cookiebanners.service.mode.privateBrowsing as 1. Make sure both cookiebanners.bannerClicking.enabled and cookiebanners.cookieInjector.enable are set as true.
It is a good option to keep the cookie banner still in the noraml browsing mode, and change just the private browsing modes.
