Corebird does not open Firefox if used as default browser

Hi,
I’m using Corebird 1.7.3 on Endless OS 3.3.13 with Firefox as default browser. Unfortunately, I can not open Links displayed in Corebird . Firefox does not open. Also if I try to add a new account and press on “Request Pin”, firefox does not open and display the url for requesting a twitter pin.

The workaround is using Google Chrome as default browser which works fine so far, but it would be nice to use Firefox.

Thanks for the reply. I did an Upgrade to Endless OS 3.3.14. Unfortunately I’m still not able to open links in Corebird using Firefox.
