When trying to install Add-ons, I am told I have version 2 and need to upgrade.

Posted

For the last few months I have problems with Youtube or installing extensions. In both instances I get a message saying I have an outdated browser (version 2), and need to upgrade. I have installed Firefox 3 (Most recently 3.6.3) multiple times, closing the old version first every time. Firefox/about shows that I have 3.6.3 installed. I even tried deleting the old version entirely and downloading the new version with Safari (I saved my bookmarks, etc. in that case). Something is very wrong, and I'm unable to install several important extensions because of this problem.

I'm using a Mac, OSX 10.5.8.

I'm at my wits end. Does anyone have any suggestions?

This happened

Every time Firefox opened

== I installed version 3.

Your UserAgent string in Firefox is messed up by another program that you installed. http://en.wikipedia.org/wiki/User_Agent

type about:config in the URL bar and hit Enter If you see the warning, you can confirm that you want to access that page. Filter = general.useragent. Right-click the preferences that are bold, one line at a time, and select Reset, Then restart Firefox
