brent some browsers do some things better than others
most cloud gaming services recommend a chromium based browser...none says anything about Firefox. Their say is that Firefox is not yet ready for online games. and it has been proved that chromium works better for gaming.However,when it comes to privacy and security it is Firefox that wins. Due to its low market share, gecko based browser are less targeted for attacks.
eye4bear yeah its concerning that it happened but Firefox still has around 19.8 crore(198 million) users who trust Firefox than other browsers. Lets hope Mozilla does some magic overnight that would give Firefox a new life 😔
And in case someone wants to see such a site where firefox is blocked then oktagon.tv might be a good example. the site works on webkit/chromium only( i discovered this from webcompat.com)
