Users who want to test it can visit the Drupal User Experience website and start playing the first video on the page. They will notice that the cursor will start to disappear for short intervals on all tabs that are open in Firefox. Tests with other web browsers revealed that some show like Opera and Internet Explorer show the same behavior while others like the Google browser Google Chrome seems to be immune and show the cursor all the time.
The problem persists even after stopping the playback of the video in question. One solution is to close the tab that contains the website with the Flickr video which stopped the mouse cursor from disappearing in Firefox. Another solution offered by Roman was to block the Flickr video script with the Firefox add-on NoScript.
Update The issue has been fixed in the meantime. When you now visit a site with an embedded video script you should not notice the disappearing cursor issue anymore. It is not clear if Flickr or Mozilla have fixed the issue. But since it is resolved, it should be the end of the issue.
