The president himself has vanished from public view, dispatching his prime minister to front the crisis.
Mr Philippe had told parliament late on Wednesday that he was scrapping the fuel-tax increases planned for 2019, after he announced a six-month suspension the day before.
Yesterday, he said he was open to studying all measures that could boost low incomes, another key “yellow vest” demand.
In another attempt to quell their anger at perceived injustice, finance minister Bruno Le Maire said France would impose its own tax on big internet firms in 2019 even if there was no consensus on a European Union-wide levy.
But in bad news for the government, protests erupted in more than 200 high schools across the country, with students setting fire to rubbish bins and a car in the western city of Nantes.
