95.75% is pretty close to solid for SameSite. Those same 4.25% of users who don't support same site are using IE6-10 (.15%), Firefox <2018 (.44%), Chrome <2016

95.75% is pretty close to solid for SameSite. Those same 4.25% of users who don't support same site are using IE6-10 (.15%), Firefox <2018 (.44%), Chrome <2016 (.35%). The amount of vulnerabilities in those browsers are huge and likely just are leaking cookies anyway through known issues that have since been patched. I'm not spending any time working bugs on IE 6-10 just to get to 100%.
