This extension implements a link at the end of the popup auth flow of Flarum that will make it possible to finish the login/registration in the new tab instead of going back to the original tab.
This workaround is required for embedded mobile browsers that use tabs/windows in place of popups and didn't implement the popup opener web API.
This problem affects multiple Flarum auth extensions, most notably FoF OAuth but also KILOWHAT Wordpress Integration and others.
This is meant as a proof of concept / temporary workaround until this gets properly fixed in Flarum directly.
composer require clarkwinkelmann/flarum-ext-auth-popup-failsafe
This extension is under minimal maintenance.
It was developed for a client and released as open-source for the benefit of the community. I might publish simple bugfixes or compatibility updates for free.
You can contact me to sponsor additional features or updates.
Support is offered on a "best effort" basis through the Flarum community thread.
