Not bad, mostly works. Full screen unfortunately goes to a separate full screen that loses closed captions. Also seems to default to where focus is on captions button so if you pause it opens the captions menu...

Can't see subtitles in fullscreen while extension is enabled

Works fine, thanks!

Thank you for making this!

wow, this actually works. you have my thanks. I'm truly amazed how incompetent HBO developers are that cant even have these hotkeys built-in!

Thank you so much.
