Auto. updates fail to install. but Firefox tells me I have the latest version.
Firefox attempts automatic updates which always fail. Then it downloads a complete version which also does not install. When directed to Firefox I'm told I amusing the latest version. Why do the updates fail, and why is it trying to update when I have the latest version???
There was a .1 update, to 25.0.1. You can check whether you have that update using
Help > About Firefox
I don't think websites can detect your version number to that level, so the Mozilla website might only be able to determine that you have 25.0.
