Same problem as above on 6/19/2012. Downloaded and installed in the plug-ins 
directory but not recognized by Firefox 13.0.1 running on OS X 10.6.8, 2.4 GHz 
Intel Core i7.

Close and restart of firefox allowed for recognition of other plug-ins, but not 
the google earth plug-in.

Same problem as above on OS 10.7.4 Firefox 13.0.1. Does this location only 
lists different people with the same bug? Is there a location indicating the 
actual solution?

Works fine with Safari 5.1.7, but not Firefox 13.0.1 on Mac OS X 10.7.4. Tried 
restarting Firefox. Tried logging out and logging in again. FF does not 
recognize that it is installed.

Same problem on FF 13.0.1 on MacOS 10.6.8. Restarting (even rebooted) and it 
does not recognize that the pligin is installed.  Plugin is clearly in the 
right folder.

Found the solution. You need to reinitialize the plugin registry 
(pluginreg.dat):

s#w_re-initializing-the-plugins-database

Did that and it works
