I have several web browsers under Ubuntu 10.10, such as FIrefox, Google Chrome. I installed Firefox first, and since I installed Google Chrome later, the default web browser for the system is changed to Google Chrome.

I can set up the default web browser to be Firefox for opening a saved html file by changing the property of html files.

But there are other applications which run the system-wide default web browser to connect to webpages on internet. Such as HTTrack.

I was wondering how to set the default web browser for the whole system? Thanks!

Thanks! Does it require to restart the OS to take effect? – Tim Apr 23 '11 at 15:18
It may need you to log out and in again, but I wouldn't have thought so. – Majenko Apr 23 '11 at 16:14

Preferred applications will work for GTK apps. Have a look also at update-alternatives --display x-www-browser and update-alternatives --display gnome-www-browser.
