when I change setting in options setting, the revert back to the previous setting; I am trying to change history to "use custom settings for history"

When I click OK it reverts back to "Remeber History"

The "Use custom settings for history" choice allows to see the current history and cookie settings, but selecting this doesn't make any changes to history and cookie settings.
Firefox shows the "Use custom settings for history" selection as an indication that at least one of the history and cookie settings is not the default to make you aware that changes were made.
If all History settings are default then the custom settings are hidden and you see "Firefox will: (Never) Remember History".
"Never Remember History" means that Private Browsing is active and "Always use private browsing mode" gets a check mark.

"Use custom settings for history" stays selected if at least one of the History or Cookie settings is not the default to make you aware that changes from the default setting have been made.
