When I made Opera my default browser, I changed all the file types to be opened by Opera. I can no longer find my way to the same list. How do I specify the default program for each file type?

@leocg Nothing. When I click on "Old Password" I see no curser and nothing appears in the text box. But I don't know what my "Old Password" is anyway so I guess it doesn't matter.

The password field is visible but doesn't allow me to enter anything. What is a "saved password" and why would I have more than one password?

@leocg Opera One(version: 117.0.5408.168)

So what is an "old password?" My only two passwords have been computer generated secure passwords saved by the browser (supposedly.) How do I obtain them? On Chrome there was a password manager which allowed me to view and copy passwords. I haven't found any thing similar in Opera. And I have lost access to all my passwords and auto-complete entries from Chrome.

I get the following message but there is no place to enter my password.
What is a "previous ... password?"

Unable to synchronize passwords
Your saved passwords were encrypted with an Opera account password which has been changed.

If you know your previous Opera account password, you can enter it now. If not, you can reset your saved passwords.
