wrong file association
 

Hello, I'm new to this forum and this is my first post! I hope I will learn here a lot and will be able to help others, one day, too.

My first question here: By accident, I changed something, and now a URL in for example an e-mail opens always in an editor (Kwrite) instead of Firefox, as it used to do! How can I restore the right situation?

problem solved
 

I've solved the problem. Configuration centre > KDE Components > File associations. There I've changed the assosiation for .html docements.
