Hi, online etiquette tip: ALL CAPS is considered shouting. No need to shout here.

Firefox has a built-in full screen feature that is turned on and off using the F11 function key. That's probably not relevant to your camera feed.

Most other full screen features are turned off by the Esc key, as you know.

Many camera/DVR feed require a proprietary plugin. If yours is like that, it may work very differently from other plugins. If moving your mouse around over the image and the corners doesn't reveal any useful controls, you should check with the supplier.

Also, your Firefox identified itself to the forum as version 45.0.2 -- that was released nearly 15 months ago, and is not secure. Mozilla discloses security flaws after each new release.

If you need to run a plugin other than Flash, you can use the Extended Support Release of Firefox 52, which is scheduled to get security updates through next May. More info:

https://www.mozilla.org/firefox/organizations/faq/ (it was designed for companies, but anyone can use it)

When you get to the ESR installer list, you'll notice at least two different downloads for Windows:

• Windows installer is the standard version for Windows that runs on both 32-bit and 64-bit Windows Vista through 10 (and 32-bit XP), the best choice for most users
• Windows 64-bit installer ONLY runs the Flash and Silverlight plugins, so that is not what you're looking for. (If someone reading this only needs Silverlight and is considering switching to 64-bit, there may be some extra file cleanup to do on your system. See: <a href="/t5/Install-and-Update/How-to-switch-from-32-bit-to-64-bit-Firefox/ta-p/36215" target="_blank">How to switch from 32-bit to 64-bit Firefox</a>)

Success?

I USE VER.45 ,BECAUSE IT ALLOWS ME TO VEIW MY SECURITY CAMS  !! (WANSVEIW )

Thank you

WANSVIEW appears to have a lot of different cameras. I looked at a couple of their manuals and found this information:

WANSVIEW has a full featured ActiveX control for Internet Explorer (OCX HYPlayer). In order to use that in Firefox, you need to install an IE Tab extension.

IE Tab embeds IE11 into a Firefox tab. It's basically IE in a different window frame. I can't see any benefit to using IE Tab for this compared with using IE11.

Could I suggest that view your camera in IE11 directly? Then you can keep Firefox up-to-date and improve your security in your other browsing.

WANSVIEW also has a reduced functionality viewer that uses the Flash plugin in Firefox. If you need the Flash plugin for Firefox, see:

• Install the Flash plugin to view videos, animations and games
• Flash Plugin - Keep it up to date and troubleshoot problems
