Hello.<br />
<br />
When I open Firefox -&gt; Youtube.com and log in, I can't see a progress bar (red) on video thumbnails. Instead I can see 'WATCHED' tag that is greyed out. How to get the progress bar back?<br />
<br />
Btw when I open Google Chrome there is no issue and I see the progress bar under my account.<br />
<br />
Thanks for any help.

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.
