Hello FirefoxUser58, any luck if you disable the YesScript 2.0 extension you have ? (you can see the latest reviews : Reviews for YesScript)

also, try disabling graphics hardware acceleration and check if the problem is there.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

1. Open Firefox Options window as follows:
2. Click the menu button and select Options
3. In the Firefox Options click the Advanced tab, then select General.
4. In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
5. Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Thank you.

Thank you for your advice TobyS5!

There seems to be a slight improvement.

The audio is more fluid but the video is still very choppy and completely out of sync with the audio.

Thank you for your advice ideato!

There's a little more improvement.

Disabling the script extension had no effect.

Disabling the acceleration did help. The audio is a little more fluid but the video is still very choppy and completely out of sync with the audio.

Overall, its still unacceptable to watch but I at least the audio is adequate.

Can you send me the link to the video, I can check it out!

Here's one but I have trouble with almost every video embedded in a web site:

Thank you for helping me!

Here is your problem, it is not your web browser it is the video, I checked it out and it is badly recorded.

This one is unwatchable on my computer:

Barely adequate audio, crappy video:

Hello,

To me it looks like your graphics card is not good enough for most videos, have you considered trying a different browser with the video and see if it does the same thing?

Thank you.

Yes, IE is no better, maybe worse.

Hello,

Well we are sorry to hear about that but it seems as of your graphics card can be outdated or not good enough to run these videos (Graphics cards like store bought macbooks can be bad) try updating it, we cannot really help with much more.

I have left a response under this including how to choose the best answer to your problem.

Thank you.

If you haven't already, please select the answer that solves the problem. This will help other users with similar problems find the solution more easily.
