Hello, Video playback on MOST websites is delayed by up to 20 seconds. Audio is always fine. I've updated Real Player (please find a way to avoid employing RP in future versions of FF along with Adobe!), updated all of my Add-ons and Plug-ins. I'm not running any crazy plug-ins. I have Kaspersky Anti-Virus running and they assure me their app. is not the issue. And I'm not allowing any Kaspersky extras to run as well. ? Ive researched the Community Forums here and outside and can find no truly viable solution. I don't want to run IE and would rather not use Chrome, but I'm getting to the point where I will if it resolves video playback. And I know this is not an issue of YouTube throttling bandwidth. ;) A few years ago all video playback worked great. Now? Not so much. Too many people are experiencing this problem. Can you offer a solution? I'm a big fan of FF and want to continue using it. Thanks, Paul

Hello,

Your profile folder contains a user.js file, which includes preferences that were not created by Firefox.

If you haven't created it yourself in the first place or aren't sure what has created it, then the user.js file shouldn't be there at all. you can go ahead and delete the file - it won't affect your stored bookmarks or other personal data...

You can remove the file manually, as described in this article: How to fix preferences that won't save


You might also need to disable the Flash Player plugin's use of hardware acceleration, which is an independent setting from Firefox's hardware acceleration setting. See:

Hello Aman, Thank you for your suggestions. Deleting the suspect file seems to have helped; I did some reading on the issue and took some time to educate myself more with Firefox's settings and diagnostic information. Thanks again!
