Your Firefox is identifying itself as Firefox 3.6.27.

Unless you are intentionally sending that information, it probably indicates an obsolete setting. You can try to clear it using the steps in this article under "Other Causes": https://support.mozilla.org/en-US/kb/websites-say-firefox-outdated-or-incompatible#w_other-causes

Any luck?
