I use firefox on my samsung tablet for uni, and have to read/markup a bunch of pdf's. On desktop firefox has all the basic features so I don't need to bother with another application, but on android I can do nothing to my pdfs. Can we please have draw, add text, comment, highlight, image, synced signature from my desktop, all the features we've got on desktop?? as it is I've had to download a seperate pdf editor even for just very simple edits.
