On Facebook flash work perfectly i think it work perfectly on every website that have HTTPS protocol in other websites like kissanime or Dailymotion it does that error
Okay, you've brought me an interesting mystery. 
If you restart Firefox from Help > Restart with Add-ons Disabled, do you have the same problem?
The videojug video loads fine for me. I'm not seeing anything that jumps out at obviously wrong, and I've never had anyone tell me that only HTTPS sites work for them before (given the size of our user population, we hear about *everything* that can possibly break, so it's rare that we get something new).
The HTTPS/SSL transport would guarantee that the content came from the site, and that it wasn't tampered with in transit. If all HTTP content fails and all HTTPS content works and that's the main differentiator, I start getting suspicious.
I was hoping that videojug also supported HTTPS (many sites will offer HTTP by default, but will serve HTTPS if you change the URL), but they don't. It would be really interesting if you could find a site that fails in HTTP but works in HTTPS. Otherwise, there are a lot of variables in play.
There was a worm going around last year targeting home routers, and it would insert fake "Upgrade Flash Player" messages into random pages. Those attacks were memory-resident, so if you power-cycled the router, the malware would get cleaned out (at least temporarily until the worm hit it again). If you haven't updated your router's firmware lately, that's probably not a bad plan in general. Rebooting the router is quick and easy, so it would be good to just rule it out.
The other possibility that jumps out is that you have malware on the machine redirecting requests. I'd recommend running malwarebytes (malwarebytes.org) on your machine. It's free and well-respected. Again, just worth ruling it out.
For the most part, all the networking stuff happens in the browser. We don't really care how the content is served (aside from some "does this have permission to talk to this" logic), because we're not really dealing with it at the protocol level. It could be that it's just better written, better funded stuff that's working well for you, as good security can be a decent proxy for the level of effort and investment in a product. Having a good 1:1 comparison would be really great for proving that it's really the HTTP/HTTPS thing. It just seems super weird.
Do you have an "always HTTPS" plugin or something in the browser? Any software firewalls or security suites (particularly free or off-brand ones), ad-blockers or anti-tracking plugins? Does this happen in regular 32-bit release Firefox, or just in the other variant that you're using?
like i said the problem is in both firefox 32-bit and 64-bit and chrome in IE it work perfectly and it get weirder i just downloaded a new browser called Vivaldi flash work perfectly in it.
I've tried everything I could think of i uninstalled flash and reinstalled it and i did the same to the browsers and to AVG internet security
