i just install the clear quantum and did nothing on it. i think reinstall will not help me.

so if you move coursor in the right down corner of full screen youtube video u have no empty space?

Please do not blockquote unneeded test like the whole response. Use as needed only https://www.w3schools.com/tags/tag_blockquote.asp

Well, by not following suggestion you leave behind all the files in the folders that can be corrupted or .... As this is a Mac refresh works better than a reinstall.

Did you ignore making a new Profile and testing also ?

Could you clarify this problem a bit more. Normally when you use the fullscreen button in the lower right corner of a video player, that is replaced by a button to return from the full screen viewer to a regular viewer. Do you mean that when you move the mouse and the controls appear, instead of having the "Exit Full Screen" icon there, you have an empty space? Does the space behave like the button or does it not do anything?

(I'm currently on a 1920x1200 monitor, so I don't think my screenshot would be very useful.)

what files if I did not shake anything and did not change it? you say strange things. I downloaded a clean browser and did not change anything in it and did not download it.

if you open the video in full screen on YouTube, and then move the cursor to the right corner. then pressing nothing will happen. you need to specifically point to the "minimize" button in the YouTube. So have u the same?

it's not critical, and I do not think it's a mistake. but in other browsers there is no empty space, and this is more convenient.

Here's what I see (attached).

The Exit Full Screen button doesn't go all the way to the lower right corner. When I click there, the video pauses.

okay i have this too. so i guess this is normal. but on chrome \ safari that button go allround. for some reasons...

The positions of elements on pages often can be modified by applying custom style rules to the page. I don't know about the player bar, but it might be possible. Can't look at it right now, but maybe after hours.

perhaps I will leave it at that. this is not critical. I will get used. Thank you.

Does it make a difference whether browser.tabs.drawInTitlebar is true or false?

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
