Is it the official Adobe Reader download website that is telling you that you are out-dated?

As far as I can see, you are running the most recent version.

Please try going to your profile folder and deleting the pluginreg.dat file and then restarting Firefox. More information about locating your Firefox profile folder can be found in this article:

• Profiles - Where Firefox stores your bookmarks, passwords and other user data

Adobe show's my version as the latest Mac Version, it's Mozilla's plug-in checker that shows it out-of-date and will not recognize it.

Did you try the steps that I have listed above?

I had already tried what you stated to do saneman said

The plug-ins checker shows Reader 15.008.20082 to be out-of-date, but Adobe's plug-in checker shows that I am up-to-date. I have erased the pluginreg.dat file and it did not solve the problem. Any other suggestions or is this the plug-ins checker not taking my Firefox Mac version into account? Is Windows still the only Reader version that has actually updated?

I can confirm that you are running the latest version of Adobe Reader, so there is no concern for security. This must be a bug on our end.

Sorry for any inconvenience.

If you file a bug report on Bugzilla, on of the developers will address this issue and my the necessary repairs.

I guess I'll file a bug report, thanks for giving it a go.

This is a know issue with the update checker. If the programs web site says you are up to date, then you are fine. Don’t worry.

No problem. Sorry we couldn't really fix your issue, but since we are not related with the development of Firefox, there is not really much that the support team volunteers can do. Thanks for contacting the Mozilla support.
