Youtube not showing the full bottom of the video

more options

Sometimes when I go to click on songs on YouTube it doesn't show the whole bottom part of the video's screen. It has some of it but does not show the fullscreen mode option to click on. When i open up Chrome it's fine. I'm using the newest update of Firefox.

They've changed something. Try to reload the website with command + shift + R.

You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be careful. If you have a password or other data for that domain that you do not want to lose, make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website, data for that website will be saved once again.

Would that work for YouTube I keep my passwords written down

Firefox 123 (110+) should keep the passwords if you use "Forget About This Site", but it is always a good idea to have a backup.

Would it forget the history of YouTube of my favorite songs and would I have to relog into YouTube if I do forget this site

more options

Yes, you lose the cookies and the history and the disk cache, so you need to login and redo site settings. You keep the bookmarks, so you can possibly bookmark important YT pages. You can do a test in PB mode as that doesn't use regular cookies and disk cache (not sure about content preferences and permissions).


You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works, you can transfer files from a previously used profile to the new profile, but be careful not to copy corrupted files to avoid carrying over problems.

What if it doesn’t work but I would still be able to use YouTube with the same Google login that I would normally do

Don't you know the credentials to login to YouTube (Google)?

You can do the new profile test first to see if that works.

How do you do a profile test

New Profile Test

This takes about 3 minutes, plus the time to test your problem site(s).

Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it.

Take a quick glance at the page and make a mental note of which Profile has this notation: This is the profile in use and it cannot be deleted. That is your current default profile.

Click the "Create a New Profile" button, then click Next. Assign a name like Test2024, ignore the option to relocate the profile folder, and click the Finish button.

Firefox will switch your default profile to the new one, so click the Set as Default Profile button for your regular one to avoid an unwanted surprise at your next startup.

Scroll down to Test2024 and click its Launch profile in new browser button.

Firefox should open a new window that looks like a brand new, uncustomized installation. (Your existing Firefox window(s) should not be affected.) Please ignore any tabs enticing you to connect to a Sync account or to activate extensions found on your system to get a clean test.

If you compare problem songs in the new profile, do they have the fullscreen button?

When you are done with the experiment, you can close the extra window without affecting your regular Firefox profile. (Test2024 will remain available for future testing.)
