A lot of this wasn`t relevant: I want my UK keyboard to work. I do not want to use the US one if I don`t have to. How does this help me fix this one key that refuses to work?Completely normal Windows behavior:
You need to understand that EN-US and EN-US International are two different keyboard layouts; what you describe is exactly how EN-US International should work and is designed to work.
This post has a bit more about differences between EN-US and EN-US International keyboard layouts: Issue with keyboard input
The chosen input language and keyboard layout can be set independently for each application and program.
What you describe is typical when, although only one input language (English US), there are more than one keyboard layouts enabled and separately set to be used on different applications. In this case it is quite obvious the EN-US International is set to be used with Firefox, whereas other apps use system default EN-US.
An example:
User has selected only one input language to be used, English (US). Within this input language both EN-US and EN-US International keyboard layouts are selected:

The input language in this case is English, with two different keyboard layouts, default US and alternative US International:
Attachment 248522
By default the fast keyboard layout switch is ALT + SHIFT.
User opens Firefox and either using above mentioned keyboard shortcut or keyboard / language icon on notification area changes the keyboard layout to US International. From now on every time Firefox is used it uses this layout instead of default US layout. Notice that selecting other than default keyboard layout only affects the application which is currently active. When Firefox is active and keyboard layout is changed, the layout only changes on Firefox.
When user then uses other apps, Word, Notepad and so on, they are still using the default US keyboard layout as long as the layout is not changed to US International for that application.
Let's say user in this example jumps between Firefox and Word. Every time Word is made active, keyboard layout is automatically switched to (default) US, but as soon as user clicks Firefox window to make it active the system automatically switches to US International layout for it is the keyboard layout selected for Firefox. And vice versa; user clicks Word to make it active, layout is again automatically switched to (default) US.

This is a very typical hardware issue, common especially with wireless keyboards. It is normally caused by bad reception, the USB receiver for instance does not pick the keyboard signal as it should causing delays.
One known reason with especially Logitech's wireless keyboards is the frequency the USB receiver uses, it being too close to some other wireless frequencies. In some cases it helps to change wireless routers frequency.

Also, as I have said possibly twice before: it is NOT a hardware issue. Please read my previous posts again if you still don`t believe me...
