Description

I use a PWA for Fastmail. Until today, clicking an out-of-scope link opened the link in Firefox. Now I get a system dialog that says "open the https link with Firefox?" and nothing happens when clicking the "open link" button.

Steps to Reproduce

1. Set out of scope links to open in browser
2. Click out of scope link
3. Click "open link"
