User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170317144518 Steps to reproduce: Go to: Under Preferences -> Security tab 1 "Use Master Password" is DISABLED. 2. In command line, "ls -l ~/.mozilla/firefox/fox.default/key3.db ~/.mozilla/firefox/fox.default/logins.json" confirms files DO NOT EXIST. 3. Confirm read/write permissions of "~/.mozilla/firefox/fox.default/key3.db". 4. Click to ENABLE "Use a master password", dialog to enter new password appears. 5. Enter password (password quality meter is at 100%) twice. 6. Click OK to set new master password, dialog "Master Password successfully changed." appears. "Use a master password" check box REMAINS DISABLED. 7. In command line, "ls -l ~/.mozilla/firefox/fox.default/key3.db" confirms file DOES EXIST. "ls -l ~/.mozilla/firefox/fox.default/logins.json" file does not exist. 8. Click to ENABLE "Use a master password", dialog to enter new password appears. "Current password:" field is NOT SET 9. Enter password (password quality meter is at 100%) twice. 10. Click OK to set new master password, dialog "Unable to change Master Password" appears. 11. Repeat steps 7-10 indefinitely. No matter what I do, I cannot use a master password. I am using Gnome Seahorse and GPG deamon, RedHat Enterprise Linux. Actual results: "Unable to change Master Password" dialog box appears after trying to enter a new master password. Cannot enable "Use master password," even after successfully creating a password. Expected results: Clicking "Use master password" should prompt me for a new password, then it should be enabled and make use of the encryption key.
EDIT: Step 3 should read: 3. Can confirm read/write permissions of "~/.mozilla/firefox/fox.default" directory.
