I cannot install the Dashlane Password Manager extension. Attempts to do so result in an interminable bouncing back and forth of the "install progress 'pong image'" I've been a faithful Firefox user for over a decade, it's my favorite browser. I've never had an issue with using the Dashlane extension. I recently did a complete reboot on my laptop to restore settings and speed but have been unable to install Dashlane after reinstalling Firefox. I'm using Edge in the meantime :(.
