Hello Firefox browser developers, I think Firefox is currently expanding the picture-in-picture mode of video websites to support adding subtitles and barrages to the picture-in-picture mode of video websites.
I am a user who uses Firefox browser to browse Bilibili, but I found that Firefox browser does not support Bilibili's subtitles and barrage functions during the process of using it.
Barrage is a very important feature on Bilibili, and it is the reason why many users choose this website to watch videos.
I hope you can adapt to the barrage and subtitle functions in the picture-in-picture mode of the Bilibili website as soon as possible, thank you very much!
