I thought FTP support had been removed a long time ago for some reason! I have very fond memories of FTP but I guess its time has come. I probably haven't used it for 10 years at this point.

The amount of complexity that one can put into a PDF is both surprising and a tad frightening.

Can't find the video but there was a sec talk where the host would demonstrate a few horrendous ones.

I instantly thought to myself .. "what could possibly go wrong?"

Is this using the browser's own JS engine? Do things like NoScript allow one to turn off PDF JS?

On the flip side, are there any examples of PDF JS being actually useful and not a vector for tracking/exploits?

I'm still waiting to see a port of Doom in one. PDFs natively support 3D models!

Print in firefox is totally broken. The change to Chromium was the last nail in the coffin for printing. The new web does not care.

I can see why they are doing it but I'll really miss FTP support. A lot of public data continuous to be distributed through FTPs and for a long time Firefox has been the easiest way to browse them.

As far as I can tell I still can't play breakout in a PDF in Firefox though (and I think that's for the better)
