How to add lfs://join= browser support after LFS has been installed?

Example: I want to click connect from LFSWorld and connect to a server. But I have unchecked this when I've installed LFS and it doesn't work at this moment.

LFS_associations.zip on the right side of page.

Cmon.. was it really so simple?

It worked, thanks! : ))
