Firefox engine or site optimization ?
Hello, there are site that do not work well in Android Firefox browser. Examples : web.whatsapp.com - sometimes I cannot type the message. I can never use dictation from gboard. 9gag.com - sometimes the site does not show anything...it just loads. Clear cache, phone restart, clear cookies, clear site data does not do anything. trello.com - I cannot move the cards around. These are just 3 example I had problems today. It's very annoying and at the same time everything I listed works flawlessly in Brave, at all times.
Is this because of Firefox engine ? or because sites are optimized more for Chromium based browsers ?
