Did you set xpinstall.enabled to 'false' long ago (due to a security issue,  since resolved) and forget to set it back?  I did.  Go to the url about:config to check/fix.

Put more clearly: 
Did you disable automatic extension installation (i.e. set xpinstall.enabled to 'false') long ago (due to a security issue,  since resolved) and forget to set it back?  I did.  
As briefly mentioned at bug 310737, the fix/ workaround is to go to the URL about:config to check/fix. (Tip: Then use "Filter" to search for xpinstall.enabled.)  
Marking as dupe.
