Why does icloud extension for firefox work in firefox 50 on one computer but cannot be installed on another
I have been using firefox on a laptop with windows 10. I have icloud bookmarks extension on that computer and it has been working flawlessly with firefox after each firefox update including firefox 50. I purchased another computer running windows ten but now when I go to install icloud bookmarks extension on that computer I get an error stating that the icloud extension is not compatible with firefox 50. Is there a workaround to manually install from my laptop to the new computer??
Thank you for your help.
