when I change privacy options to "custom settings for history but Firefox does not remember this and always reverts back to "remember history"
I clicked tools/options/privacy and changed option from "remember history" then ensured "accept third party cookies until expire" was enabled then clicked ok.
Next time I checked tools/options/privacy the settings had reverted to " remember history"
Why? and what do I do next

Firefox shows the "(Never) Remember history" choice if all the history and cookie setting are the default.
Make at least one change to the default setting if you want "Use custom settings for history" to stay selected.
Otherwise Firefox will revert to "(Never) Remember history" if you return to the Privacy tab.
The choice "Use custom settings for history" will stay selected as long as not all settings are the default to make you aware that you made changes.
