I’ll be emailing the site admin… or some contact at the site, but, is there anything else that can be done to try to put pressure on these websites that tell me “you’re not getting the best experience… download Chrome.”?
I know Firefox has a “Report a broken site” feature, but, the site isn’t technically broken. They’re just telling me to switch browsers.
My favorite situation that happened few times already was when I sent a link to webpage that worked for me in firefox with no problem to someone using chrome and it told them to use chrome.
