[Solved] Resizing YouTube Player Window: Dealing with 20-30% Size Reduction Across Browsers

Hello

I have a very difficult problem to solve due to the size of the player on YouTube. Until now it was like this:



And now it is done like this:



In other words, the player's size decreased by 20-30%. I don't know if I clicked somewhere or pressed any key combination or what, but that's how it was done. I immediately say that this is not a problem with enlarging / reducing the page, I checked it already and it is not from that. It's the same in every browser, only when I log out or log in to my other YouTube account is the player window is normal (large). When I log in to the first account, the window turns small again. Clearing cookies does nothing. On another computer (clean system) it's the same. On another computer (also a clean system) it is the same. On other internet access it is the same. Nor is this a problem with cinema mode or anything. This is a problem with the size of the player window in "normal" mode, without zooming, without cinema mode, without fullscreen. The size of the player window is "drawn" from the account from YouTube because when I enter the code of the page I have in the line written:

Yes, but that's not it, because it has not decreased by zooming in / out in the browser but it has decreased through YouTube. Anyway, filming doesn't do anything - it's still a small window.

Ctrl + 0 - nothing happens.

Firefox, Windows 10.

Check https://www.ghacks.net/2014/04/06/enable-dynamic-player-size-youtube/

Also gives nothing. After entering these commands in the console, the window is still small. Anyway, I have recently tried it too.

I wrote, although it is the second time I write there. I doubt that the increase in my number of clone submissions will affect Google finally taking care of it.

EDIT
When I enter the console from the YouTube account to which a small player window has been assigned, I have:



And when I enter from another account with a normal window, I have this:

If you use the YT account on the mobile version, maybe there is a problem somewhere here that saved such settings. It could be a tablet, phone or even TV could mix up the settings.

He tried to clean out temporary files or restore browser settings where you have used this YT account.

I used YouTube on many other devices (e.g. friends) but I logged out later. Unfortunately, it is not possible for me to clean temporary files there. Either way, I don't think that's the reason.

It looks like the settings have been saved to your account, which is why the same problem occurs everywhere.

Rather, you will not do anything about it yourself, since there is no suitable option to change it.

Well, and Google does not respond to requests. I tried to report it to my company and I was even called by a lady but said that she did not do it and that it was not possible to pass the case on or to the appropriate department.

Contacting Google support is very difficult. You can submit only through the opinion or on the forum https://productforums.google.com/forum/#!forum/youtube Only that in this forum no one will help you in such a "complicated" case, because no one knows anything and you what they know they don't have contact with each other. There are no phone numbers, nothing at all.

So advise the user alone. For an IT specialist it's probably just a matter of clicking on an option.

Google has removed the problem after many of my reports. I waited half a year. I reported the matter both through the opinion (in Polish and English) and through the Google forum. It's best to write that they remove the so-called "flexy mode". I wrote this way:

Please remove the flexy player mode from my YouTube account.
Please remove the player flexy mode from my YouTube account.
