It works for me if I open the player in a new tab via the right-click context menu (This Frame > Open Frame in New Tab).

I see a security error in the Web Console (Firefox menu button or Tools > Web Developer), so it is possible that Firefox is blocking content, possibly because the main page is HTTP and the cam player is a secure link. It works in the current Firefox 38.5.0 esr release and in Firefox 42.

It worked this morning ok before the update to version 43.0.1 . Right clicking like you did works for the cam but nothing else on the page, chat page, etc. I made sure my 'players are up to date etc. Works ok on Chrome. Sometimes I wish they'd leave things alone.

Thank you for your attention and reply

OK, I checked it further and it work if I enable third-party cookies. I normally allow third-party cookies from visited website, but that isn't enough in this case.

I have it set for 3rd party too and delete on closing. I added the website to Exceptions but that isnt working either.

I had it add an Exception and still not working https://thecrush.tv/deer-cams/live-deer-cam

First let me say how much I appreciate you and taking the time to help! I can get to the page but the cam section is just black. If I right click , This Frame, Open in New Tab , I can see the cam working but not the whole page like normal. I tried all you just suggested above to no avail.
