[BUG]: Autofill works only for Password field (Firefox)

[formeo14]

What happened?

In Firefox, the autofill functionality works correctly for the password field on Cosmos login pages, but it does not work for the username field. Additionally, this issue is reproducible when using Bitwarden on both mobile and desktop platforms. Users are unable to autofill their username, leading to a suboptimal user experience as they must manually enter their username each time they log in, while the password is automatically filled.

What should have happened?

Both the username and password fields should be autofilled when saved credentials are available, regardless of the browser or password manager being used.

How to reproduce the bug?

1. Open Firefox on desktop or mobile and navigate to a Cosmos login page.
2. Observe that the password field is automatically filled if the user has saved credentials.
3. Notice that the username field remains empty, even though saved credentials are available.
4. Repeat the test using Bitwarden on both mobile and desktop platforms.
5. Confirm that Bitwarden is unable to autofill the username field, while the password field is filled correctly.

Relevant log output

<input aria-invalid="false" id="nickname-login" name="nickname" placeholder="Enter your nickname" type="nickname" class="MuiInputBase-input MuiOutlinedInput-input css-9qsxsj" value="">

Other details

I think the name has to be name="username"
