Firefox is set as default but certain things still open in Opera

[Rytron]

Hi.

I have Firefox set as my default web browser. However, if I choose 'Browse' in Kompozer to preview the newly changed HTML file or select 'Open URL' in Keepassx -- both instances open in Opera. How can I make these always open in Firefox?

Thanks.

Would removing Opera be a valid option?

I also have Chromium, if I removed Opera it would then goto Chromium. I like to have 3 browsers.

Will this [link](http://www.howtogeek.com/117709/how-...ubuntu-4-ways/), especially the part about using update-alternatives, help?
