Steps to reproduce: 1. Load Manage my add-ons landing page https://addons-dev.allizom.org/en-US/developers/addons 2. Click the "Delete" link from a listed theme. 3. Click the "Delete Theme" button without entering your password 4. Close the Delete Theme floating window. 5. Reopen the window by clicking the "Delete" link for the same theme. Expected results: The Delete Theme window has no design or layout issues. Actual results: The password text field remains highlighted even though the window was closed. The highlight is cleared if the page is refreshed. Notes/Issues: Verified on FF19 (Win 7). Screencast for this issue http://screencast.com/t/DhbcXCWqgq9

This is a non-issue. This is how native form validation works in Firefox.
