892506 - Autocomplete/Passwordmanager automatically fills in first field on website with a wrong value

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[stein]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20100101 Firefox/23.0 (Beta/Release)
Build ID: 20130708202947

Steps to reproduce:

Discovered this bug in the backend of Wordpress - so if you can, please log into a WP backend. I happen to see this bug on other pages, but this seems to be the best to reproduce the error.

- log in to some wordpress backend
- go to Posts > Categories
- click on some category to edit

On every let's say 4th to 8th load the first field of the form is filled with my first name in lowercase.


Actual results:

The first form input field is filled with my first name in lowercase. Even if the field has some predefined values (in case of WP the category name coming from the database) it is sometimes overwritten.

Happens like every 4th to 8th time when loading the page.

The name or id of the input doesn't matter. It fills in my first name (I don't know why it is the first name in lowercase) with field names like 'EMAIL', 'name' and new names like 'SJKGASF-whatever'.

The dropdown known from the password manager is not displayed if I enter the field and try to delete the value.


Expected results:

Firefox should let the pre-filled field value as it is. (as it did before)

Please check if the issue occurs using Firefox in safe mode (with your addons disabled):

Or on a new, empty profile:

I am sorry I forgot to test it with addons disabled and wasted your time :/

It seems the KeeFox addon for KeePass is triggering this behaviour. I need to sumbit the bug there it I think.

Sorry again!

No problem, thank you for supporting Firefox.
