This extension used to be perfect, but recently (since around Jan/Feb 2021) I've been having problems with the extension (on Firefox and Chrome). Whilst on YouTube, I tend to keep my main YouTube window open whilst browsing for things to watch, then open any videos I want to watch in a new tab. When I do this, quite often the video won't resize to my configured prefs for the extension, and I have to reload the page to fix it. Also, the video seems to stall when opened in a new tab (but the controls suggest it is playing), so I have to pause and then resume the video to bring it to life.

It's a great extension, there's nothing that can compete with it (that I've found), hopefully these issues will get resolved.

I'd also appreciate proper changelogs with each release. 'Bug fixes and improvements' tells me nothing when I'm hoping to find news of these issues being resolved with each update.
