I believe you will find it is disabled not deleted if you look at your addons.

You can force 5.0 "compatibility" with the "Compatibility Reporter" extension, or with extensions.checkCompatibility using about:config. Use either or both at your own risk. I understand that works for "Google Toolbar".

More information with links in my profile.

Extension author's are responsible for their own extensions. Google is the author of the "Google Toolbar", it is their responsibility to maintain it whether if means real code changes or just upping the version limitations.

I'm a little concerned about the "at your own risk" aspects. Any idea as to when the problem might be resolved?

I did the installation procedure Reporter Add-on Compatibility extension but continued the same way does not work in FireFox 6.0! Is not there like in this version?

@ TCanuto

"This version" being what version? I thought in Firefox 5.0 Google Toolbar was added to the blocked list, but I guess not

Compatibility Reporter adds a "Compatibility" drop-down to extensions where maxVer is not current. Since the developer has not marked it a compatible, you would have to enable the extension. (Developer marking as compatible means he thinks it is compatible but it is not the same as upping the maxVer, or actually coming out with a newer and better version).
