Facebook’s profits soared 61% spurred by growth in mobile users at the end of last year, the company announced Wednesday, as co-founder Mark Zuckerberg said 2017 had been one of the company’s more difficult years as a public company.

Zuckerberg has vowed to fix the issues at the social network, amid concerns it was used as a platform for Russian meddling in the US elections. Facebook was also criticized over censorship and the addictive qualities of social media.
