Firefox Issue

[PhilMacbook]

I use my Mac with multiple desktops (I think they used to be termed spaces). Since installing Mojave (MacOS 10.14) the Firefox browser window appears in all desktop spaces not just the one I opened Firefox in.

I am runnng the latest version of Firefox. Does anyone know a fix for it?

If you have the Firefox icon in your Dock, right click on it and select Options from the pop-up menu. Your answer might be there. It should be obvious.

Doh! Thank you.

It's funny as I never knew about or set that feature, it somehow switched on when I upgraded to Mojave.

It's great to have it back to normal.
