Should You Accept Cookies?
First-party cookies are generally fine - they enable login sessions and shopping carts. Third-party cookies are tracking cookies used for advertising and are the main privacy concern. Most modern browsers now block third-party cookies by default (Firefox, Safari, Brave) or are phasing them out (Chrome).
Cookie Consent Banners
Under GDPR and similar laws, websites in many countries must ask for consent before setting non-essential cookies. You can generally click "Reject all" on these banners to decline tracking cookies while still using the site.
