Browser suggestion insertion does not work on login in Mozilla Firefox.

Steps to reproduce:

1. Login with checked "remember me" checkbox
2. Logout
3. Open login form and start writing username
   Browser's suggestion list should be shown
4. Select option from suggestion list via down arrow and click enter

Actual result: no any changes in login form - just what was typed before
Expected result: chosen suggestion have to be inserted in to login form

Works as expected in Chrome
