Hello, I am Firefox Android user and i am having issue with Firefox while browsing substack.com website, When i open that website from a chromium based browser it works well but in Firefox it is slow and in my old mobile(android 9) which is even slower and i never wanted to open it. Twitter(X) is also heavier to open. I stopped using it from Firefox and using a chromium browser for these logins. Firefox has all the features i wanted and i am satisfied that it is better than any other browser but lacks in performance. It is not smooth as Chromium browser. Please look into it and it would be great if it just be more smooth like Chromium based browsers. Thank you
