You can try to clear the YouTube (Google) cookies to see if that has effect.

Hi,

Thank You for reply. Yes I have cleared all google and Youtube cookies and I still have this issue. Now I've checked also on Edge and it's working like it used to

You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

• hold down the Shift key and left-click the Reload button
• press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• press "Command + Shift + R" (Mac)

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Remove the Cookies" for websites that cause problems:

• Options/Preferences -> Privacy & Security
  Cookies and Site Data: "Manage Data"

"Clear the Cache":

• Options/Preferences -> Privacy & Security
  Cookies and Site Data -> Clear Data -> Cached Web Content: Clear

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

I have tried all of them already - without improvement unfortunately.

As I have this issue only in Firefox (Edge and Chrome shows YouTube correctly) and I have checked on 2nd PC with the same result (Only Firefox is not showing progress bar and video length) I have checked Firefox update history and I thing this is related to update 82.0.3 done last week.

I nearly always use YouTube signed out. I don't know why it would be different signed in. ??

Since I already grabbed today's update to Firefox 83.0, I can't check with your version, but it looks okay in a quick test logged in in a private window:

That's really strange. I am on 2nd PC now and I have the same issue. See screenshots for 3 scenarios - Signed-In in Firefox, Signed-Out in Firefox and Signed-In in Chrome.

If it's not release issue it might be my google/youtube account setting (but I have checked through it and have not seen anything related) or maybe some localization differences for Polish version of Firefox(?)

One more thing: when I opened Youtube signed-out in Frefox I have noticed video duration has showed with small delay vs thumbnails so I am thinking if there's something that could block it from being downloaded.

Google is constantly experimenting on us. It's quite aggravating.

I think the delay in the appearance of the overlaid time is because it is generated by a script that runs after the basic layout is built. Not sure whether that is a clue of any kind?

Similar thread on Reddit (not a solution):

https://www.reddit.com/r/firefox/comments/jvda4r/firefox_no_longer_showing_youtube_video_length_in/

I see this HTML code in the Inspector.

This Reddit topic seems to be exactly same issue - I will follow it also. I have checked inspector and I have "overlays" while I am signed out but I cannot find it when signed in

Edit: I have signed in to my 2nd gmail account and switch to Youtube - there's no issue with video length bar. They are appearing immediately.

Hi, It seems everything is back on track again and I can see video length again. Thank You all for your answers.
