If you right-click in the Web Browser, you have a nice option to install several others.
I noted that it is not working anymore in two different Mabox computers (mine included). Checking the script there is an innocuous pamac-installer failing to install whatever package you pass it as parameter. There is a short window opening/closing very fast where you can’t see any error; with journalctl, also, couldn’t find any related error.
