Like when I choose to open a new URL in a firefox tab, it will keep all new firefox instances under one window.
How do I do that with konqueror?
I’m not sure I understand the question but when I’m using konqueror or
firefox I’ll open up new tabs with the keyboard shortcut CTRL-T and/or click
on links with the centre mouse button to keep my browsing organised.

kev.
Say I called konqueror in Akregator, I want a new tab in the “one” konqueror window, instead of a new window.
Settings>Configure Konqueror>General and tick Open as tab
SOLVED ] After googling for hour, finally found it. 
Configure Desktop->Default Application->Web browser->Open http and https URLs in an application based on the contents of the URL.
