I am using Firefox latest browser version 120. From one month, youtube is annoying me with a message window randomly which says "adblock is not allowed on youtube, buy youtube premium". My nephew suggested to use Chrome browser for youtube so i don't get these adblock warnings. I tried playing youtube in chrome with same youtube profile on which i got adblock warning. Surprisingly there is no warning on chrome. So google is targeting firefox users to warn about adblock.
There is also another issue with firefox and youtube which is serious. When logging to youtube from firefox, youtube saying that my browser is not secure and just displaying a retry button. After pushing the button for 5 times, I am allowed to login youtube. Google is trying to kill firefox like this.
