Avoid the lag when entering/exiting fullscreen on a YouTube video - by hiding the heavy fluff while transitioning

Image from store YouTube Fast Fullscreen Toggle
Description from store There's an annoying lag period when entering/exiting fullscreen on a YouTube video. On my machine, it's normally ~2 seconds; but with a large playlist expanded, it gets up to ~3 seconds. This extension reduces the transition time to almost nothing. Supported fullscreen transitions: - Clicking the fullscreen button - Pressing the F key - Double-clicking the video Unsupported fullscreen transitions (still slow): - Escape - F11 Note that Firefox doesn't seem to have the same issue as Chrome; so in Firefox the improvement is barely noticeable. In Vivaldi, there is unfortunately an intermediate step in the fullscreen transition, which I can't seem to do anything to avoid. It appears to be due to the toolbars being hidden/shown at a different moment to when the browser actually enters/leaves fullscreen. Technical detail: This bug's been present for years now, and I got so sick of it that I spent one night experimenting to find a way to avoid it - and I found one! The extra HTML content on the page (playlist, recommendations, comments, description, likes, etc.) is pretty heavy, and when you toggle fullscreen, YouTube moves it around in the DOM, which ends up incuring a fair bit of processing. I've worked out that it's significantly faster to hide that extra content before transitioning, then display it again afterwards once it's reached its new position.

  • (2022-05-30) Dani Cute: WOW! I didn't think it would work but it did. I have no idea why Youtube is so slow and can't do what this extension does. Well, it's expected since they lasted 100 years to implement a dark mode.

  • (2022-03-26) Curtis J.: It works!
  • (2022-03-12) Tyler: Epic programming skills. Provides a MASSIVE difference on my decently high end system (I7 8700k overclocked, RTX 2060 Super) Before around 2 seconds, sometimes 3 seconds on big playlists pages. Now 0.5 seconds. It's still not the the instant it used to be back in the good ol flash days, but massively better. Thanks man.
  • (2022-02-27) Adarsh Nair: It works better than the default transition but sometimes shows a grey bar for a few seconds on the player where the media controls (pause, volume slider, timer) are. Sometimes the transition gets slowed down when there's multiple tabs on chrome and takes around 3 to 5 seconds. Please fix this issue. Other than that, there's no issues and it works great! Thanks for this extension!
  • (2022-02-24) chunkymonkey: works perfect on Chrome 98.0.4758.102. is WAY faster now.
  • (2022-02-19) lorenzo checcarelli: I have an i7 11700K and rtx 3080 ti, 32gb RAM DDR4 4000Mhz CL16. And it works only once every 30 times ahahahah. The Youtube site is badly optimized, this extension is even worse. Do not download it, It works only when it want ahahah. The developer is even worst than google ones.
  • (2022-02-16) DarkYuan (DarkYuan): Totally better than default! From up to a 6 second lag to less than 1 second. Not as fast as Firefox though, but I can live with this so long as I can stay on Chrome.
