@ragnar2099 Unsupported browser is up to the website. They choose to write their website for Chrome or Edge and then tell any other browser it isn't supported, even though there is no difference.
On a few sites they don't like the ad blocker or tracker blocking, but most of the time they just can't be bothered to support a browser that's just not as popular. If they let you "Proceed anyway?", do so. If they don't, install a user-agent switcher extension to tell them you're "really" using Chrome.
