Officials have vowed zero tolerance for the violence that has marred the weekly protests since they began two months ago, deploying some 80,000 security forces nationwide, AFP reported.
In Paris, epicenter of the fiery street clashes and vandalism that have made global headlines, 5,000 riot police were on hand, using tall barricades and armored vehicles to lock down the central Place de la Concorde and surrounding districts.
Hundreds of officers were also on guard on the Champs-Elysees, where banks, jewelry stores and other shops had boarded up windows in anticipation of renewed looting and violence.
Yet many cafes and retailers on the iconic avenue remained open for business, as several thousands of protesters marched calmly from the Place de la Bastille toward the Arc de Triomphe early in the afternoon.
Many sang the "Marseillaise" national anthem, while others held signs saying "Insecurity is not a job!"
At times the crowd yelled "Free Christophe!" in reference to Christophe Dettinger, the former professional boxer arrested last week after being filmed bashing two police officers during the Paris demos.
Police said some 30 people had been detained in the capital earlier for carrying weapons or other charges.
"We've come to Paris to make ourselves heard, and we wanted to see for ourselves at least once what's going on here," said Patrick, 37, who told AFP he had travelled from the Savoie region of western France.
In the well-heeled horse racing town of Chantilly just north of Paris, 1,000 or so protesters marched through the center before descending on the hippodrome where they delayed the start of a race, local media said.
And another 1,200 protesters gathered in the central city of Bourges, where some yellow-vest organizers were hoping to those from areas far from the capital.
Signs said "Macron resign!" and "France is angry," while local prosecutor Joel Garrigue said five people had been detained after police discovered a cache of ball bearings during a search of their car.
The protests also spilt over the border into eastern Belgium late on Friday, where one of around 25 protesters manning a blockade died after being hit by a truck, Belgian media reported.
Officials had warned of bigger and more violent protests than last week, when demonstrators rammed a forklift truck through the main doors of a government ministry in Paris.
"Those who are calling to demonstrate tomorrow know there will be violence, and therefore they are in part responsible," Interior Minister Christophe Castaner said in a Facebook interview Friday with Brut, a digital news site favored by many yellow vests.
But many yellow vests pointed to images of a police officer repeatedly striking an unarmed man on the ground during a protest last week in Toulon, accusing the police of excessive use of force.
The movement, which began as protests over high fuel taxes, has snowballed into a wholesale rejection of Macron and his policies, which are seen favoring the wealthy at the expense of rural and small-town France.
Macron has called for a national debate starting next week to hear voters' grievances, hoping to sate demands for more of a say in national law-making and tamp down the protesters' anger.
He has already unveiled a 10-billion-euro ($11.5 billion) financial relief package for low earners, and axed the planned fuel tax hike.
But the public consultations risk being hobbled by record levels of distrust towards politicians and representatives of the state.
A poll by the Cevipof political sciences institute released Friday showed 77 percent of respondents thought politicians inspired "distrust", "disgust" or "boredom".
And Macron may not have done himself any favors on Friday, when he told a gathering at the Elysee Palace that "too many of our citizens think they can get something without making the necessary effort."
