Fullscreen button opens `chrome-extension://` and fails on Firefox-based browsers

[sun-yryr]

Clicking the fullscreen button in the popup navigates to chrome-extension://{uuid}/index.html, so the page won’t load in Firefox-based browsers.

Steps to Reproduce

1. Install PR Monitor 0.10.7 on a Firefox-based browser (e.g., Floorp [email protected])
2. Open the extension popup
3. Click the fullscreen button (clone icon) in the top-right corner
4. Observe that the browser navigates to chrome-extension://{uuid}/index.html, which fails to load

Expected Behavior

• On Firefox-based browsers, clicking the fullscreen button should open moz-extension://{uuid}/index.html and successfully render the fullscreen view.

Actual Behavior

• It opens chrome-extension://{uuid}/index.html, which fails to load on Firefox-based browsers.

Environment

• Browser: Floorp [email protected]
• Extension: PR Monitor 0.10.7
