Super new to lineage, just successfully installed on an old Samsung tablet!

If I click a link to a pdf file in the browser, the pdf is downloaded and I have to select it to view it. I need pdfs to be displayed inside the browser directly. Is this possible with the buildin browser and how? And if not which browser would you recommend for this?

NB: no google play, so things have to be side loaded, if that matters to my question.
