1741889 - Specifying a URL port number leads to hostname being interpreted as a protocol

Status: RESOLVED DUPLICATE of bug 1618094

(Firefox :: Shell Integration, defect)

Description

[Will Shanks]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

With the flatpak version of Firefox, type an address that includes a port number into the address bar, for example localhost:8888.

Actual results:

The "Choose an application" dialog appears looking for an application that can open "localhost" links.

Expected results:

Firefox should have defaulted to http://localhost:8888 for the address and opened the page served by a web server I have running locally.

Other notes:

• If I type out, http://localhost:8888 then the page loads normally.
• If I type "loc", Firefox will suggest previously loaded pages like localhost:8888. If I then select that as is, it will open the page by inserting http:// in front. However, if I edit it to localhost:8889, it will not insert the http:// and will result in the "Choose an application" dialog (even if defaulting http:// were not generally desired, it is a bad user experience not to fill in the http:// here when autocompleting a previously opened http url).
• If I use the non-flatpak version of Firefox, localhost:8888 opens the page without the http:// just fine.
• This problem also affects sites other than localhost. That is just the most common case for me. Typing in www.google.com:443 also results in the "Choose an application" dialog when using the flatpak but opens the page normally for the non-flatpak version.

Caused by widget.use-xdg-desktop-portal: true, noticed it after enabling portals on non-flatpaked firefox, but was too lazy to report.

Arg, I don't know how #1618094 didn't come up in my searches.
