I've seen this on a few sites and it sounds like this person also experienced this. It happens on Linux and Window. I don't think it's a new bug/behavior.

I'll use vanguard.com as an example.

1. Visit investor.vanguard.com site. Click that you'd like to log on. 2. I'll be placed on a login.vanguard.com page that displays a Username field and a Password field. Because I've logged in before, those fields are yellow and filled in with the proper values. (In the case of the password field, it's all stars, but when I click to reveal the password, it's the correct password.) 3. Click on the "Log In". 4. The browser rerenders the page claiming that the userid or password is wrong.

But if I follow the above steps, but add a step:

2.5. I slightly edit both (one is not sufficient) fields, removing a character and putting it back in so the values are edited but not changed. As I do this the fields become white instead of yellow.

Now when I reach step (4), I'm actually logged in without complaints.

The underlying AJAX request is pretty cryptic, so I can't quickly spot/debug what happens at that level, but I assume the page is not passing the field values visible as yellow. on the page.

Am I misunderstanding how the yellow auto-fill works? (On most sites it works as I expected and no reediting the autofilled fields is necessary.)

Can this be fixed or should I put up with it?

Hey folks and folkins.

I save all my passwords to my firefox.

I created a password for privileged access to my firefox at configuration time at some service. Recently (about half a year ago!) I created a new user at the same service (the same domain). The new login was used two times and is now stalled to log-in. It was simply a monitoring user.

Each time I visit the domain I get prompted with the monitoring user instead. I can not simply focus the username and select my previous user from the drop-down. Nor does firefox-password learn my preference (which is a good thing, I guess).

Nonetheless: I have to delete the username, write the first character of my user and then I can select my password. I find it cumbersome since I do this multiple times a day.

Imho there are privacy solutions which could be applied. I don't see any existing options in the UI.

Sincerly, Thomas

Hello, when I am using a login form, it sometimes suggests an email I can use, but I do not want this behavior in case I am sharing my screen. And some of the emails that are suggested are also not mine to begin with, so I simply do not want Firefox suggesting it to me.

I would like to disable this feature altogether, but I have looked online, searched the settings, and yet I found no way of disabling this. I even confirmed that my Firefox Passwords doesn't have any entries, so I don't understand where it is getting these emails from. I would like help with disabling these suggested emails.

FF 147.0.1 (64-bit) Linux mint 22.3

Hi everyone, for some time (~2weeks) I have the issue that I don't get any autofill-information in login screens.

I checked the relevant settings/passwords/"Fill usernames and passwords automatically" (OK) I deleted my ff profile and reinstalled ff. (whereas here it worded briefly) I disabled all plugins (only have "uBlock Origin" running at the moment)

I'm pretty puzzled, does anyone have any ideas? Best, Stefan

I recently got a new machine and loaded it with Linux Mint 21.3 - Cinnamon, FF 142.0 and Bitwarden Version: 2025.8.2 along with the usual cadre of extensions that I use on every other machine I have.

When I first start Firefox, Bitwarden autofill suggestions does not work, autofill from the "Fill" button in Bitwarden does not work and returns an error. The only thing that works is to individually and manually copy the username, paste it, then copy the password and paste it.

If I log out of Reddit and then try to log back in, the autofill suggestions works and the "Fill" button also works.

This is only on Firefox and only on the fresh start of the app. This does not occur on Chrome and I have not tried (and don't want to try) it on Windows.
