small fixes

[progressify]

Hi
I have used your project and I have added some small fixes at Puppeteer
I have also updated the Puppeteer version to the latest

Can I submit a PR? Or do you want to discuss what I have done?

Hi @progressify, I haven't had the time to maintain this repo for a long time, however, if you'd like to submit a PR I would be more than happy to review and merge this.
