I wonder if its YouTube’s bug but why its only happened on linux? I have dual boot, when I was using windows it’s saved the configuration for theater mode. (thanks for your answer, ad least now I can make sure that there is no miss configuration from me which makes any weird behavior to browser)
Are you sure that it was the browser itself that did that, or was it a browser extension you had?
I know that browser extensions exist that do this ─ I’ve seen them but I’ve never installed them ─ so I presume that by default, a browser doesn’t know how to save this preference, and that it’s a YouTube decision to not respect the preference for theater mode.
Im pretty sure I don’t have any special extension to control my media for youtube. my extension mostly like react-dev, redux-dev, some vpn stuff, or ad block if I used firefox. its not a big problem tho but its just kinda bug me to click theater mode over and over everytime I reboot system or just restarting browser
this probably could a thing too, but if they can save the volume preferences(the volume does not reset after restart browser) or darkmode, there must a way too to implement it on theater mode preference.
