issues with background playing videos

it seems that after an update to the firefox android app it seems that the background music stopped working as it should. it does continue playing but it's just that it keep pausing. i am on youTube and this app used to work as long as you don't close the tab it continues playing in the background. and i did not know that firefox background playing issue was an issue in the app. i wish to have the real background playing. i enjoyed using firefox mobile android app but it went downhill. i am so disappointed and i left the app android system: android 12 ram 8GB model name : Samsung Galaxy S10
