Hi,

When trying to download addons from Mozilla's website, it says:

"To install this add-on and thousands more, get Firefox, a free and open web browser from Mozilla."

However, I am using Firefox 3.6.13. This occurs on other websites too, such as I can't use Google Docs because it says I don't have a compatible browser. So in summary, websites don't think I am using Firefox. Thank you for helping :).

Yup, something you installed has butchered your UserAgent.
