You really shouldn't be using a browser in this day and age for running MC, you should be using the Desktop App for MC which has many benefits, including getting around a major Chromium 'issue' with all versions of MC up to and including the current early preview versions of MC 2026. Desktop App for MC - So much better than in a browser
