more options

When I visit YouTube a message popsup telling me this:


- Your browser is no longer supported. - Please upgrade to a modern browser.

Next Screen:


- Hey there, this is not a commercial interruption. You’re using an outdated browser, which YouTube no longer supports. Some features on YouTube may not work.

- Please upgrade to a modern browser. Here are a few options: IE8 - Opera - Safari - Crome - Firefox

And then a green message appears on the right of the video telling:


- You are using an outdated browser, which YouTube no longer supports. Since some features on YouTube may not work, you are viewing a lightweight version of the video page. Go back to the regular page

And It's not letting me to Expand the Video window....

Well, I believe it may be with your Flash Plug-in. You may go to Tools > Add-ons and see if you can upgrade it.. It will be under extensions. or If needed try upgrading complete flash on your entire computer.. If that does not work REPLY to this post.

Your user-agent indicates that you have/had the MegaUpload Toolbar installed and that can interfere with your system recording the correct version of Firefox. Your user-agent is showing (most likely in error) that Firefox 2.0.0.11 is what you have installed. See:

iliasv82: Your version of Adobe Flash is current. You can check the status of some (not all) of your plugins here: http://www.mozilla.com/en-US/plugincheck/

  1. Finding your version of Firefox (and your user-agent): https://support.mozilla.com/en-US/kb/Finding+your+Firefox+version
    • Note: The user-agent can be found by clicking Help > About Mozilla Firefox; the user-agent will be the last 2-4 lines.
  2. To uninstall a toolbar or other extensions or to troubleshoot extensions and themes, see:
  3. You will also need to reset a preference.
    • Reset general user-agent
      • type about:config in the URL/address bar and press the Enter key
      • if you see the warning, accept it (promise to be careful)
      • Filter = general.useragent
      • items in bold and that indicate user set; right-click that preference and select Reset
      • restart Firefox (File > Restart Firefox)
