For years now i have used X-Notifier Firefox add on for checking emails, i like the way if i have new mail then i just click on its tab and it opens a new gmail/hotmail tab account that received the mail. Since the latest versions of firefox it can no longer work, is there anything similar that anyone uses with the same or similar functions as i prefer this to using a seperate email client.
is your issue known here? https://addons.mozilla.org/de/firefox/addon/xnotifier/ --> https://addons.mozilla.org/de/firefox/addon/xnotifier/reviews/ latest should work with firefox v50 https://addons.mozilla.org/de/firefox/addon/xnotifier/versions/ but that requires v50 beta (1).
