Keyboard shortcuts in Firefox don't work as expected

Previously, on Ubuntu and other systems, the following shortcuts in Firefox would work:

• Ctrl+Tab - Switches between tabs
• Ctrl+F4 - Closes current tab

Since installing the Mate desktop (Gnome 2), the shortcuts do the following:

• Ctrl+Tab - Does nothing
• Ctrl+F4 - Closes Firefox

I've checked in the "Keyboard Shortcuts" section in Mate, but neither of these are being overridden. Compiz isn't installed.

This is rather annoying.

The Firefox extension "FoxTab 1.4.5" was responsible for breaking these shortcuts. Disabling it restores the desired functionality.
