How do you safely restore an old brick chimney to use - the mortar is cracked and falling off?
Don't hire just any bricklayer. Repointing is a exacting and separate skill from bricklaying. Most important, the old and new mortar formulations must be identical, so the repairs have the same density and rigidity (not just appearance)!
If the existing mortar crumbles easily, this indicates the mortar is too weak (perhaps from the use of sand that contained dried sea salts).

Do you need chimney liner for inside chimney?
To start off, a Chimney Liner is a clay ceramic, or metal conduit installed inside of a chimney. The main purpose of a Chimney Liner is to contain the combustion products, direct them to the outside atmosphere, and to overall protect the chimney walls from heat and corrosion. You need a Chimney Liner because the flue gases are acidic and will literally eat away at the mortar joints from inside the chimney. As the mortar joints erode, heat transfers more rapidly to the nearby combustibles and dangerous gases such as carbon monoxide can leak into the living areas of the home.
