OK, I can tackle this one.
Napoleon's famous law code (the Napoleonic Code) represented in many ways a retreat from the more socially permissive laws of the Revolutionary era, although not totally. The most famous of these changes was making it far more difficult to obtain a divorce. The Revolution had legalized divorce, but Napoleon added many hoops to jump through to the divorce procedure, including a three-year ban on remarriage after a divorce (Napoleon only waited three months after his divorce to remarry). This law saddled many French women with husbands they were not particularly thrilled with.
Napoleon's commitment to the idea of equality for loyal French citizens did lead to the enactment of Emancipation of French Jews from the various legal disadvantages and granting full citizenship to them. Napoleon famously held a Sanhedrin (or Jewish court) of prominent rabbis under orders to answer a list of questions the Emperor had about Judaism. An example of these questions: "Do the Jews born in France, and treated by the law as French citizens, acknowledge France as their country? Are they bound to defend it? Are they bound to obey the laws and follow the directions of the civil code?"
The Emperor also passed the Concordat, regranting the Roman Catholic Church permission to operate relatively unharried by the French state but without returning the vast ecclesiastical lands seized by the Revolution.
Another big social change was Napoleon allowing many of the emigres, French figures who had fled the Revolution, to return to France. The previous Revolutionary governments, even the conservative Directory, had no desire to let the emigres return home.
One final move I'll bring up is the reintroduction of slavery. Slavery had been banned in 1794 and was reintroduced by Napoleon in 1802, and the reintroduction of slavery was directly responsible for reopening the Haitian Revolution, which had previously settled on a tenuous compromise of Haiti as an autonomous province of France governed by ex-slaves. Napoleon sent an expedition to Haiti under the command of his brother-in-law Charles Leclerc to restore slavery to Haiti, place it back under French administration, and to capture Toussaint L'Ouverture. The Leclerc expedition succeeded only in the third of these tasks but failed in the first two as Leclerc and most of his men died of yellow fever and Haiti formally declared full independence from France in 1804. In the end slavery was only reintroduced to two French territories, the tiny islands of Guadeloupe and Martinique, where it would remain in place until 1848.
