Thank you for reporting this to Ubuntu. Do you have firefox-3.5-gnome-support installed?

ii firefox-3.5 3.5+nobinonly-0ubuntu1 safe and easy web browser from Mozilla
ii firefox-3.5-branding 3.5+nobinonly-0ubuntu1 Package that ships the firefox branding
pn firefox-3.5-dbg <none> (no description available)
ii firefox-3.5-gnome-support 3.5+nobinonly-0ubuntu1 Support for Gnome in Mozilla Firefox

Even though the package says gnome-www-browser is provided, it does not show up in:
/var/lib/dpkg/alternatives/gnome-www-browser

Same problem as Firefox 3.5.

Deferring to Beta 2

Chris, this used to be done with an update-alternative, but hasn't since Firefox 3. I'll let you decide if we want this or not.

This will be fixed in package Firefox

We will be changing all versions of Firefox to the package Firefox no more versioning in the name and all our releases will be updated to latest stable version of Firefox releases.

This bug was fixed in the package firefox - 3.6.3+nobinonly-0ubuntu2

I was able to confirm that this bug exists with Chromium on Ubuntu Lucid Lynx. I am very new to this bug business, so if I did anything wrong, please bear with me.

fixed released in:
chromium-browser (5.0.375.29~r46008-0ubuntu1) maverick
chromium-browser (5.0.375.38~r46659-0ubuntu0.10.04.1) lucid-security

that was 2 months ago, strangely LP didn't auto-close this bug.
