I have been catching up downloading attachments from my emails. A popup notified me of the latest download for Firefox Browser. As always I said yes and went back to my downloads. Suddenly I downloaded a pdf and instead of having the opportunity to save it, it opened up. I downloaded it to my files. When I did, my email had closed without my signing out. After reopening my email 3 times and not signing out, the email locked me out for about 10 minutes. Any ideas? I think I need to go back one version of Firefox.
