Youtube and some other websites report that my Firefix isn't updated, but in fact I have the most recent version of it (3.6.8)?!

I have the latest version of Firefox 3.6.8.

Problem occurs when I go to Youtube or few other sites where I get message "Your browser is no longer supported. Please upgrade to a modern browser." I can remove that alert and continue to browse on Youtube normally afterward, but every time I come back again to Youtube same message appears.

Why is that happening and how can I fix that?!

Thank you in advance,

Your loyal user.

Hi ivan,

Your User agent is wrong

1. In the Firefox Location Bar, Where you enter the address of web pages, enter about:config

2. A This might void your warranty warning may appear. Click I'll be careful, I promise!

3. In the Filter text box, enter general.usergent

4. For each of those general.useragent preferences, right click them and choose reset
