Why isn't the Sign In Problem fixed? I can't sign in with a previously useable password, and posted 'solutions' are meaningless.

1. Doesn't recognize previously recognized password so can't sign in; 2. No email received for whenreset attempted, although response was that a message was successfully sent; 3. Can't reply to related article because I can't sign in.

Hi, the issue is case wise I would think and is seen as a new address. If want the other account use the other email address.

The username, there, differs casewise from the one I used when I registered after asking my first support question (I.e., one is XXXXxxxx@gmail.com while the other is xxxxxxxx@gmail.com)

1) Are you using any Password Manager besides Firefoxes?

2) Such e-mail is always sent to the address on file with the website.

Check your user profile at the site. Also, check your junk mail folder.


Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

1. I'm using only LastPass; Firefox PM is unchecked. 2. Not sure what you are saying, here: Which website?

You say, "Check your user profile at the site." By site Do you mean my Firefox app account profile?* The username, there, differs casewise from the one I used when I registered after asking my first support question (I.e., one is XXXXxxxx@gmail.com while the other is xxxxxxxx@gmail.com)

You say, "Check your junk mail folder." I am using Gmail, thus I use no "Junk mail folder" or junk label. I did a Gmail global search for Mozilla messages and found no confirmation email.

The problem remains in Safe Mode.

  • BTW, I have no problem signing in to the Firefox app and managing it.
