have you downloaded the latest flash player using Firefox to download it, note FIrefox uses a different flash player than in chrome (pepper) and IE (ActiveX).

yes....version .......11.8.800.94....I still can not open any videos. When I click on the video, nothing happens

I do not see your latest answer

Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash update and/or a malfunctioning browser plugin such as Real Player.

In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:

• Flash Plugin - Keep it up to date and troubleshoot problems

• Adobe Flash plugin has crashed - Prevent it from happening again

• Flash 11.3 doesn't load video in Firefox

How am I supposed to watch you tube or Fox News on Firefox browser? This message is displayed:

Java Deployment Toolkit (click-to-play) has been blocked for your protection.

Click the lego icon in the location bar and hit allow.

What lego icon?

What is your answer to my question , How am I to watch videos on Firefox when ......Java Deployment Toolkit (click-to-play) has been blocked for your protection.

You don't need the Java Deployment Toolkit to watch videos on YouTube. Go ahead and completely disable that plugin/extension here:

orange Firefox button (or Tools menu) > Add-ons > Plugins category
orange Firefox button (or Tools menu) > Add-ons > Extensions category

Hopefully that will remove the spurious message and we can get closer to resolving your issue.

I DID. i STILL CAN NOT PLAY VIDEOS

Hi rxman1975, do you get a different error now?

Have you tested in Firefox's Safe Mode? That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Any difference?

Does not work

Hi rxman1975, do you get an error message? What exactly is happening when you go to a page with a video? Maybe give a URL and describe what happens for you.
