FireFox appears to be telling web servers that I am running 3.0.10 when I am on 7.0.1 for OS X

My laptop died and I migrated to a new one running OS X Lion using Migration Assistant.

Now, several websites are telling me that I am running an old version of FireFox and to update. Example: plus.google.com

I tried adding a plugin to allow me to specify my version but that is not working as well since the browser reports the wrong version to the plugin manager. https://addons.mozilla.org/en-US/firefox/addon/prefbar/ says: Not available for Firefox 3.0.10

I am running version 7.0.1 on OS X 10.7.1 (looking at the details below, you are showing very different versions.)

Please help.

Thanks, Jacob

You have a pref general.useragent.override that changes the user agent.

Thank You! This solution is far better than the sync, purge, and reinstall solutions I had seen before. Do you think this setting was added by one of my plugins? I cannot imagine doing it myself. I do all kinds of things to my browsers, but typically emulating an older browser is not one of them.

Again, Thanks, Jacob

That user agent shows a GoogleToolbarFF (GTB5) part, so that toolbar is a likely suspect of a change that happened in the past (2009).
