Just how are you installing these extensions?

Hi Matt,

     Thanks for replying to my posting.
    Added the Canadian Dictionary the "Regular" way and it worked.
    Should have been suspicious that on my old laptop the enabled add ons each had an image in  
   the square box on the left side of each line showing the enabled icons - but I figured they were
    enabled so the image did not matter.   However, the Canadian Dictionary in the Dictionaries
    list did have an image in the square.
    SO.....decided to try loading the extensions via the "from a file" method instead of the "normal"
    method (search and select etc).    Downloaded a few xpi files and loaded them - Eureka!!!  They
    worked.    My concerns of something serious being wrong are gone.   Turned out to be a simple
    solution to my problem.    However, I am curious as to why the xpi file method works and the
    usual method I have used for years does not.   I'm curious but finding the reason would be
     beyond me.   So I am happy and going to catch up with my mail.
     If you can replicate my problem - Emoji is one extension you could try loading - I would be i
    interested in hearing what you discover.
    Regards,    Fred
