Hello.

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode (don't forget to select Disable all add-ons when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and theme and this one for plugins.

If you need support for one of your add-ons, you'll have to contact its author.

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")

Finding your version: https://support.mozilla.com/en-US/kb/Finding+your+Firefox+version

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.~~

Update Java: your ver. 1.6.0.03 (~~red:very old~~); current ver. 1.6.0.20 (important security update 04-15-2010) (~~red:Firefox 3.6 and above requires Java 1.6.0.10 or higher~~; see: http://support.mozilla.com/en-US/kb/Java-related+issues#Java_does_not_work_in_Firefox_3_6 ) (Windows users: Do the manual update; very easy.) ~~red:Check your version here~~: http://www.mozilla.com/en-US/plugincheck/ See: Updating Java Do the update with Firefox closed.

Hey!

Thank you so much TX Guy and Morbus for helping me out. I went to about:config and did what you said and it worked. I did not have Megaupload at all I guess there was something wrong. Anyway, now things are ok. :)

Thank you once again.

TC

You're welcome.
