After updating to Firefox 43.0.1 Firefox does not display this live webcast. Link to location of live webcast : http://www.packers.com/media-center/live-webcasts.html

1st picture, With Firefox 43.0.1 Player looks completely blacked out. (player inside blue box )

2nd picture is Google Chrome, ( player inside blue box ) This is how the player looks normally, when they are not broadcasting. Internet Explorer shows the same as Google Chrome.

Refreshed FF, closed and reopened, No change

Please advise Thanks,

Attached screenshots

If you have problems with current Shockwave Flash plugin versions then check this:

  • see if there are updates for your graphics drivers

https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. Is the problem still there?


Start your Computer in safe mode with networking. Then start Firefox. Try Safe web sites. Is the problem still there?

Well that knocked out Classic Theme Restorer, Crap! It is gone. Is there away to restore FF to before I put it in safe mode ? Trying fix one problem which creates another is a drag! Oh, by the way, safe mode did not fix the live webcast problem.

What safe mode stopped the problem?

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.


It could be the work of one of your add-ons. Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control>(Mac:<Command>)<Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is detective.

No, When I put FF in safe mode there was no change. When I put FF back into normal mode. Classic Theme Restorer was uninstalled.

That is odd.

Enter about:config into your Firefox address bar Click the I'll be careful button Find xpinstall.signatures.required in the list Right click the preference Select Toggle until the value is false


Classic Theme Restorer (Customize Australis) {web link}


Have you tried the Computer in Safe Mode?
