> PDF.js is slow, buggy, and can’t edit documents.

That is leagues ahead of native PDF plugins which are slow, buggy, full of vulnerabilities, closed source, require a deprecated plugin infrastructure and usually can't edit documents either.

PDF.js is one of the better things to come out of Mozilla.

Okay. But the solution is to not involve the browser at all. It's there to browse. Once you find and download the file have it open in a real application designed for reading pdf.

Ideally, yeah. But often PDFs are integrated with the web experience as another web page. Or atleast that's how I treat them. I have 2-5 research papers open in my tabs at all times, and I browse through them like I would with any other article.

Sure if it piques my interest I would download it, organize it but I wouldn't go through the pains of doing that for every pdf I lay my eyes upon.

You don't have to do that. Just set your browser to open the file in a real application. It'll automagically download to some temp dir (ie, /tmp) and you won't have to care about file paths or organization at all (unless you want to).

I have tens of research papers open in my tabs at all times. But for a good experience reading I open the full text in my pdf reader.

PDF.js has had a huge amount of its own vulnerabilities.

I don't think you've spent any time with regular people. The vast majority of the world finds computers to be confusing. The less buttons they have to click the better. All they want really is another appliance that has fixed functionality.

You're being needlessly down-voted here (I can only guess at what silly HN tripwire you've activated) but you're absolutely right. Tech people like us might think it's completely obvious that a browser shouldn't render pdfs or make your toast. But end users don't care. Browser x lets them read stuff quicker without switching to another app. They want the monolith.

We can dislike it, but we need to reconcile it.

Yeah, and I know this first hand. I work at a biotech startup and we have some super intelligent people who regularly get confused with modern UIs. For e.g. Not everyone understands that the hamburger menu is actually a menu. Or that flat shaded text can actually be a UI button element.
