Takze sa ospravedlnujem, nasiel som riesenie.

hi, in firefox 63 the autoplay preferences are reorganised in preparation for this feature shipping out of the box in one of the upcoming versions. in about:config you can set media.autoplay.default to 1 in order to block automatic playback on all pages or set it to 2 to decide on a per domain basis.

Mozete oznacit ako vyriesene.
