Must restart Firefox to see Wallet icon

I finally was able to get Wallet to work on the Firefox browser, however, when I first open Firefox it doesn't show the icon in the upper right tool bar.  The Wallet prompt to sign in pops up as normal and I sign in - but the icon still doesn't appear in the tool bar. I have to close Firefox and reopen the browser for the Wallet icon to appear. This has to be done EVERY TIME I open Firefox. Anyone know the fix to getting the icon to show on first opening?
