I have updated to Firefox version 3.5.9, but every time I go to a website (in this situation, Netflix) it tells me the browser is not supported, and it requires "at least Firefox 2.0."

This happened

Every time Firefox opened

This has gone on since I've used Firefox

User Agent

Something you installed has changed your user-agent.

See: http://en.wikipedia.org/wiki/User_Agent

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)
