https://www.youtube.com/html5 YouTube Test Page: What video does this browser support

Thank you for your reply to my question. My graphics drivers are up-to-date. I have reported the crash, but found no solution on the Flash site. The Flash player Test page suggests that I have the right version of Flash to function with Firefox: both of these have recently been uninstalled then reinstalled. The YouTube Test Page does not seem to be relevant to my particular problem. Despite all this, the Flash plug-in crashes when I attempt to view Flash videos on http://www.railcam.uk/site/watchbasic.php. It is fairly easy to join the site and free, if you think the problem is perculiar to the site, however ... There is no problem when using Microsoft Edge on this PC, nor is there a problem when viewing the same videos on a different PC using Firefox. What next, please? Cheers Ralph

This is not a cure, but should let the web page load without crashing.

Flash block {web link} Never be annoyed by a Flash animation again! Blocks Flash so it won't get in your way, but if you want to see it, just click on it
