Loading indicator is still displayed when opening out-of-scope URLs in a different browser

[joulev]

Description

See title. I'm not sure if this is a bug or not, but it's definitely unintended behaviour to me.

Steps to Reproduce

1. Install any apps. For example install example.com
2. Enable "Open out-of-scope URLs in a default browser"
3. Click on an out-of-scope URL. In example.com there is the "More information" link that goes to an out-of-scope URL.
4. The link is opened in my default browser as expected; but the app window icon is changed to the loading icon (and since the page is never opened in the app browser, the loading icon is always there until I force-reload the page by using ctrl+r or similar). I don't think this should happen.

What should happen

I think at least the out-of-scope links shouldn't trigger the loading icon. I would even prefer that the loading icon is never triggered by any links, out-of-scope or not, though this is purely personal preference.

Affected Websites

I reckon this will happen anywhere. But I've tested and found this bug on

• discord.com which is where I mainly use the extension ← whenever I click any links, the loading indicator will stay there until I force-reload or close the app
• example.com which is the reproduction I wrote above

Environment

• Operating system: macOS Sonoma public beta
• System architecture: Apple M2
• Installation method: Homebrew + Firefox extension store
• PWAsForFirefox extension version: 2.7.3
• PWAsForFirefox native version: 2.7.3
• PWAsForFirefox runtime version: 2.7.3
• Firefox version: 116.0.1

Yeah, it's a bug. I'll try to fix it.

You can also hide the loading icon so it never appears. If you want to do this, add the following CSS to your userChrome.css:

@-moz-document url('chrome://browser/content/browser.xhtml') {
  .tab-throbber {
    visibility: hidden;
  }
}

You can find instructions for creating userChrome.css on the website. Follow the steps that are mentioned there, but copy this CSS instead of those from the website.
