The reason Ctrl-F4 doesn't work in KDE is because KWin uses the same keyboard shortcut for switching between workspaces. If you would really want to use Ctrl-F4, you might want to consider editing the KWin keyboard settings.

To do that, open System Settings and go to Shortcuts and Gestures.

System settings

Then navigate to Global Keyboard Shortcuts and choose Kwin from the KDE component dropdown.

Kwin

Scroll down all the way until you see Switch to Desktop 4 option. Click on the shortcut and choose Custom and either select a different shortcut or leave it as empty.

Removing the shortcut

You should now be able to use Ctrl-F4 to close tabs in Firefox.

Solution 2

In Xubuntu, keyboard shortcut settings can be find in this path: Settings→Settings Manager→Window Manager→Keyboard

I observed that the shortcut for closing a tab in Firefox/Chrome/Chromium (Ctrl+F4) doesn't work on KDE. It seems it is being intercepted by KWin.

Is there any fix or workaround for this problem?

If you don't want to do all this then just use Ctrl+W instead. It works perfectly in Linux Mint 15.
