Bug sat in the previous component for a month with no action. I'm going to move it to another component to see if someone going to look at it...

I took a look at the 302 response:

The location header shows that the server returns a Firebase Dynamic link and it seems that GeckoView doesn't handle this well.
Hence, change the product to GeckoView.

I can reproduce this in Fenix. The form page gets stuck in a redirect loop.

It seems like there is something special about the forms.gle redirects on Android. In Fennec, Focus (GV), and Klar (WebView), tapping the forms.gle link above causes Android to ask if it can open the forms page in my default browser. In Fenix Nightly and R-B, tapping the link shows a brief flash of loading bar animation but the browser stays on this bug page.

This likely just comes down to Fenix not handling intent:// URLs.

Is forms.gle sending a different redirect to Gecko than to Chrome? Kevin recalls a similar Google Sheets bug. He said he'd look for that bug.

[Chris Peterson [:cpeterson]]

This is a Fenix bug. Fenix needs to add support for intent URIs, or at least recognize them so we don't get stuck in an infinite loop.
