Comment 20 for bug 220575

So far, it looks like anyone using Firefox 3.x and Kubuntu are having this issue. I just went to another PC running KDE and it had this problem too. Most people are just "used to it" but I simply can't so I want to find a fix. It's certainly fixable for KDE as per the instructions in https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/194624 (installing gtk2-engines-qtcurve and selecting the QtCurve theme) but for users of Gnome in Kubuntu (like myself) it doesn't fix it. Yes, I know I probably shouldn't be using Gnome if my distribution is Kubuntu but I decided to make the switch and changing distributions at this time would require too much time. Besides, I'm not sure if this problem is specific to Kubuntu or not.

So, if anyone has a solution for Gnome, I'd (and many other people) would appreciate it!
