Firefox updates latest version, but sites like You Tube don't recognise it.
I've installed the latest version of Firefox, but when I visit YouTube, it still displays the message that I need to update to the latest version, as mine is not supported, even though I have the latest version!
This happened
Every time Firefox opened
== YouTube introduced the changes.

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. See: http://en.wikipedia.org/wiki/User_Agent http://kb.mozillazine.org/Problematic_extensions (scroll down to "MegaUpload Toolbar")
To uninstall a toolbar or other extensions or to troubleshoot extensions and themes, see: http://kb.mozillazine.org/Uninstalling_toolbars http://support.mozilla.com/en-US/kb/Uninstalling+add-ons#How_to_uninstall_extensions_and_themes http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes
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.extra.firefox -the item will be bold and show user set -right-click that preference and select Reset -restart Firefox (File > Restart Firefox)
Other Issues: ~~red:You have installed plug-ins with known security issues. You should update them immediately.~~
You ~~red:MAY~~ need to Update Adobe Reader for Firefox (aka Adobe PDF Plug-In For Firefox): your ver. N/A; current ver. 9.3.3 (important security update release 06-29-2010; see: http://www.adobe.com/support/security/bulletins/apsb10-15.html) ~~red:Check your version here~~: http://www.mozilla.com/en-US/plugincheck/ See: http://support.mozilla.com/en-US/kb/Using+the+Adobe+Reader+plugin+with+Firefox#Installing_and_updating_Adobe_Reader You may be able to update from the Adobe Reader installed on your system instead of going to the Adobe site and downloading. Start > Program Files, find and click Adobe Reader to open, click Help, click Check for Updates. If you go to the Adobe site to download the current Adobe Reader: -use Firefox to download and SAVE to your hard drive (save to Desktop for easy access) ~~red:-See the images at the bottom left of this post to see the steps to take on the Adobe site~~ -exit Firefox (File > Exit) -check to see that Firefox is completely closed (Ctrl+Alt+Del, choose Task Manager, click Processes tab, if "firefox.exe" is on the list, right-click "firefox.exe" and choose End process, close the Task Manager window) -double-click on the Adobe Reader installer you just downloaded to install/update Adobe Reader
- NOTE: On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen). See this: http://vistasupport.mvps.org/run_as_administrator.htm
- NOTE for IE: Firefox and most other browsers use a Plugin. IE uses an ActiveX version. To install/update the IE ActiveX version, same instructions as above, except use IE to download the ActiveX installer.
