Open out-of-scope links in external browser opens and leaves a blank window

[jmadren]

Description

Before the latest update to 2.14.1, opening links from the PWA GMail app worked ok, though it would flash a new, blank window before opening the link in a tab in the main Firefox window. The blank window would immediately close. A little annoying/distracting, but ok.

After updating to 2.14.1, the blank window no longer automatically closes. I have to close it manually. And it's not reused if I click on another (or the same!) link in gmail. Always opens a new, blank window. This window shows the URL of the link in the header.

Steps to Reproduce

1. Go to gmail in a PWA (don't know if other PWAs exhibit this, as gmail is the only one I use)
2. Make sure 'Open out-of-scope URLs in a default browser' is enabled
3. Click a link in an email that should open a webpage
4. See issue

Additional Information

Capture of the blank window header is attached.

The 'When opening a link that should normally open in a new window or tab' options don't seem to make a difference in the above behavior.

Environment

macOS 14.7.2
Firefox 136.0.1
PWA Extension 2.14.1
PWA Native 2.14.1
PWA Runtime 136.0.1

Well, it seems to be fixed now. I was continuing my troubleshooting and tried disabling 'Open out-of-scope URLs in a default browser', then testing a link (which did as expected - displayed the webpage in the PWA). Then I re-enabled the out-of-scope setting and now it works great! Not even a flash of a blank window - it just opens the link in a new tab in the main (default) Firefox browser with no other artifacts or unwanted behavior.

Maybe some code path that didn't activate until the setting was toggled?

That's weird and I don't know why it happened. As it's fixed, I'll close this issue. If it happens again, please let me know and I'll reopen and try to fix it.
