Web browsing with plasma-mobile

[Gobelin]

I run PostmarketOS with plasma-mobile UI.

I have 2 browser installed :
- Firefox
- Angelfish

1- Firefox is running quite well, specially with the customization found here. However, I struggle to find a way to get a virtual keyboard running (the virtual keyboard from the distro do not show up when placing the cursor in a text field.

2- I can't run Angelfish : it launches, but impossible to load a page. I got this error :

Code:

pinephone:~$ angelfish

Do you know were to report bugs for angelfish ?
Did you manage to use any web browser with touch UI on postmarketOS ?
