@roytam1 In Serpent v52.9.0 (2025-01-10) (32-bit) on website playground.ru the video player doesn’t work, giving "Player error: t.c.ChangeType is not a function" and "TypeError: Argument 1 of Document.elementFromPoint is not a finite floating-point value" also appears in the console. Link to check: https://www.playground.ru/exodus/news/byvshie_tvortsy_mass_effect_raskryli_eschyo_bolshe_detalej_o_svoej_ambitsioznoj_igre_exodus-1745326 I suppose to fix "Player error: t.c.ChangeType is not a function", it’s necessary to add support for SourceBuffer.ChangeType() method, which was added in Firefox 63. To fix "TypeError: Argument 1 of Document.elementFromPoint is not a finite floating-point value", it’s necessary to add support for MouseEvent.x and MouseEvent.y properties, which are aliases for MouseEvent.clientX and MouseEvent.clientY properties respectively, and were added in Firefox 53.
