A version of my master password is permanently stuck, visible, in the login screen for all to see.
In other words, in Firefox on my laptop I click the BW icon and the verify identity screen drops down. The problem is the master password field is already populated with a row of black dots which anyone can read by pressing Show. The visible password isn’t exactly the master but it’s close. It is a mis-type I entered and then corrected.
It’s only on my laptop. My phone is all OK.
It isn’t part of Firefox history, it doesn’t seem to related to Firefox extention permissions - how do I get rid of it please??
Thanks @dh024, that got an immediate result. But still questions left.
I found that if in Firefox settings I un-checked “Autofill logins and passwords” The problem vanished, if I re-checked that it came back. So Firefox is the problem - thank you!
However, I had previously thought of Firefox. But what I’d done was to search the list of Firefox saved logins (all of them, manually) and found that Bitwarden was not listed. I now checked again and it looks like the BW login is called
moz-extension://e12d8a62-0d15-4726-b033-ecd1f73b1fab
I’ve now deleted this and also put it in the list of exceptions and the problem is fixed.
The question remains how, if I wanted to put BW in the list of FF login exceptions to not offer to save, I would know this magic name.
However that’s unimportant now, so this issue is sucessfully closed. Thanks again.
