Genuinely wondering here, what are the benefits people are liking here? Whenever I open up a pdf it opens up fine in chrome. A side note if anyone is also security conscience. Over the years I have also grown wary whether safe to also download pdf's and open them with a pdf reader. Anyone know if there is a best practice how to trust the pdf when opening on your host machine, or what do you suggest?
