Konqueror is a worthy and noble browser, I'm sure, but I have got used to Firefox over many years and prefer to use that for all internet browsing. I have tried all the tricks I know of - I have been into the Control Centre and changed the default browser, I have reinstalled Firefox and answered "yes" to the question of setting it up as the default etc. But when I click on links in other applications - even Thunderbird - it still starts up Konqueror.

So where is it I REALLY should change this behaviour? Surely there is some text based configuration file somewhere in the system?

My HW is ADM64, OS is Debian (testing), KDE is 3 (where do I see that ,exactly?).

You can find your KDE version by going Any KDE application > Help > About KDE.

Thanks for your reply - I suppose I should have stumbled over that one, but that wasn't what was first in my mind when I asked about the default browser.

You seem to imply that I am in breach of the code of conduct, and I have gone over what I have written. I can't see where I am impolite, inconsiderate or any other such thing - perhaps you would care to elaborate?

I did try to search before I asked, but the search engine doesn't seem to quite give me what I look for - I get either too many answers or none at all, depending on the search string; maybe I just don't know the right question to ask. Maybe somebody else knows to answer, then?

Actually that is his signature He didn't write that to you in specific! Just for example your post also says this: "janpla, proud to be a member of KDE forums since 2008-Nov."

See under the "bcooksley's signature" box here: http://forum.kde.org/bcooksley-u-21.html

What bcooksley has written applies to all forum members, and are guidelines that users and we mods (should) follow.

@janpla

Please try as root

"update-alternatives --config x-www-browser"

and select iceweasel.

melkart: that worked, thanks!! Not what I would call a very intuitive procedure though.

If this thread is resolved, could you please add [SOLVED] to the beginning of the thread subject. Thanks in advance.
Apologies about the misunderstanding of my signature.
