#### Problem description
"View saved logins” option appears with server login and passwords suggested in the decryption passphrase field in Firefox browser.
The prefilled passphrase (or prefilled password while login in to server) sometimes contains wrong prefilled password.
#### Steps to reproduce the problem
1. Save some passwords (e.g. server login and password) in the browser.
2. Go to an encrypted project in Central.
3. Go to a form with some submissions.
4. Go to Submissions tab.
5. Click "Download x Submissions”.
6. When the dialog opens, click "CSV” or "ZIP” button to download.
7. If the passphrase was prefilled (in my case some wrong passphrase), warning appears "Could not perform decryption. Double check your passphrase …”.
8. Remove the prefilled passphrase and click the passphrase field.
