What would be some good approaches to writing a browser extension that allowed the browser to view *only* HTML pages that contain links to a particular type of file (PDF)?

Inconsistently. Broken HTML typically causes a problem at the parsing stage, before the browser even gets as far as rendering. The errors prevent the browser from creating a valid document object model, so the browser will make the smallest set of changes (adding/removing/altering elements) necessary for a valid DOM. How the HTML is rendered depends what changes were made. HTML5 has well-defined rules for how to correct errors in a document’s HTML. I would be very surprised if all the modern browsers strictly followed all those rules, but the list gives good examples of how browsers deal with the problems. Some of them are simply recording a convention that was already common. Historically, how browsers corrected errors in HTML was a matter of the development team’s choice. This meant that different browsers often made different choices. Sometimes t would come to adopt the same solution over time, sometimes the differences would persist. HTML 5 has not brought an end to this pattern. The browser wars never really finished. Have a look at the accepted answer to this Stackoverflow question for an example of how two different browsers have made different choices in fixing a broken HTML page.

Write on PDF: All You Need to Know

There may be an easier way. When it comes to HTML parsing and rendering, not much can actually be done to get around browser behavior. This means that HTML5 will have to fix these issues on an iterative basis. As a result of this, HTML5 will likely introduce some standards that are meant to help browsers deal with these issues. What these standards are is up for debate. Many will agree that a number of them are good. And what will happen is that different browsers adopt similar sets of standards. This will be similar to having different versions of Java installed on your computer, so that you all can get to use the same APIs. It's worth keeping this in mind, as the adoption of HTML5’s standards will likely be closely associated with how the browsers deal with these problems. What browsers will adopt this The following is all speculation.
