From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: The General Preferences Dialog use to have a way to set Firefox as the default browser. Now is missing Updating the browser, KDE lost the default browser setting. I can't set firefox as the default browser. Version-Release number of selected component (if applicable): firefox-1.0-2.fc3 How reproducible: Always Steps to Reproduce: 1.Select Edit->Preferences->General 2. 3. Additional info:
The default browser thing was for GNOME only, and it did not properly integrate with everything (which you are seeing if you clicked on it at any point -- it should never need to be changed with each upgrade, but it set itself up stupidly, which is why I disabled it in the first place). In GNOME, the correct way to set it up is to use gnome-default-applications-properties (Main GNOME menu > Preferences > More Preferences > Default Applications). This is what the default application thing in Mozilla tried to do but failed. Not sure how to do it in KDE, but since this was a GNOME thing only, it probably won't have an effect on you unless KDE reads settings from GNOME. In that case, use the suggestion here to fix your default application and it will never need touching when you upgrade.
