Since version 66 update cannot delete auto login & password information
I have cleared all history & cache. Deleted key3 & 4 .db files manually removed cache data, but website still retain ids & passwords. I cannot check 'ask to save logins & passwords' box. It is greyed out!
That could be the form filler built into Firefox. Click in the field, enter a character or two and STOP ! Using the arrow keys, highlight an unwanted entry. Then press Delete (Mac=Shift Delete). Repeat as needed.

You can check your saved logins here:
- Windows: "3-bar" menu button (or Tools menu) > Options
- Mac: "3-bar" menu button (or Firefox menu) > Preferences
- Linux: "3-bar" menu button (or Edit menu) > Preferences
- Any system: type or paste about:preferences into the address bar and press Enter/Return to load it
In the left column, click "Privacy & Security".
Then on the right side, scroll down to the Logins & Passwords section.
Click the "Saved Logins" button. Here you can view/edit passwords ("Show Passwords" button) or delete logins completely.
