I sometimes hate Firefox because only this browser has lot of issues which doesnt gets resolved quickly and I didnt found any support email id of Firefox them where I can directly contact them. All of a sudden Youtube is not working, keeps on loading, no audio and video in youtube. Another website called Duolingo where the audio is not coming. I have reinstalled freshly firefox almost 4 times now and still facing this issue. I can able to do everything in Microsoft Edge and Opera browser. Only Firefox is nerd where I dont know there are no plugins I have installed nor I have any weird extensions. Permissions are allowed to play audio and video but still firefox browser is not working. Is there any solution for this or should I just simply uninstall this browser and get rid of all problems facing because of this browser? What solution can anyone suggest here?
