There have been a half dozen vulnerabilities found in the Firefox extension code exploitable through PDF.js over the years, but this is a far better record than the hundreds of vulnerabilities identified in Acrobat Reader.
PDF.js does a lot less than Acrobat. It's much more focused on just displaying articles, and less about rich media interactions like embedding 3D models, Flash, videos, etc. in the PDF.
> The Cathedral of Saint Peter of Beauvais is a Roman Catholic church in the northern town of Beauvais, Oise, France.
> From 1569 to 1573 the cathedral of Beauvais was, with its tower of 153 meters, the highest human construction of the world. Its designers had the ambition to make it the largest gothic cathedral in France ahead of Amiens.
> Victim of two collapses, one in the 13th century, the other in the 16th century, it remains unfinished today, only the choir and the transept have been built.
And they were definitely competing with each other to build the tallest and most spectacular cathedral. There wasn't an official record book, but the architects were always aware of who was claiming to be tallest. If they didn't want to take the claim for granted, it was easy enough to go measure it yourself.
Just for one example: Ulm Minster was specifically designed to be taller than the one at Cologne:

It's actually a little ungainly-looking for that. The tower is out of proportion to the rest of it.
It wasn't just cathedrals. They were doing the same things with bell towers. The Leaning Tower of Pisa doesn't need to be that tall -- and if they'd built a more reasonably-sized tower, it would have been more stable.

If you are interested in the architecture and engineering of gothic cathedrals, I highly recommend the 2010 arte documentary "Cathedrals" - unfortunately, I was only able to find a German version:

If I remember correctly, it discusses the structural weaknesses of several cathedrals (including Beauvais).

And anyone into church architecture should also watch "Churches: How to Read them", which I believe is on youtube.

Too bad I wasn't able to find the english version of the OPs link in German. Looks good.
