Ctrl-F4 closes two tabs, not one. Ctrl-W is working fine. This is possibly due to a plugin / extension, as I have updated them / installed new themes recently.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the Safe mode start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Thanks - I was hoping there was a known solution to this, as I didn't want to go through the tedious procedure of switching extensions on one by one. I guess I'l have to resort to that, will post an update then.
