User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

1. Use the Firefox Flatpak build.

2. Install "chrome-gnome-shell" package.

3. Install Firefox GNOME Shell integration.

4. Go to "extensions.gnome.org" and choose any extension.

(This is on Ubuntu 20.04, vanilla GNOME session.)

Actual results:

An error report shows that says the native host connector cannot be detected.

There is no option to install the GNOME extension.

Expected results:

I should be able to install the chosen GNOME extension directly from the website and manage it afterwards.

The behavior is correct on the current RPM/DEB builds.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Jan, any idea here?
Thanks.

The GNOME Shell integration browser extension uses native messaging to communicate with a host program that talks to GNOME Shell, so it is a case of bug 1621763.

Because this bug's Severity has not been changed from the default since it was filed, and it's Priority is P3 (Backlog,) indicating it has been triaged, the bug's Severity is being updated to S3 (normal.)

This is still a problem with snap version of Firefox 93 (build 631).

Please disregard my last message - Wrong bug! :(

Can confirm the problem for Firefox 98.0.2 with flatpak with ubuntu 22.04.

Yes, this is a duplicate of bug 1621763. Until native messaging will be supported in flatpak portal we can't do much about it.
