Basically turns ff.net into AO3, more or less. Sucks you have to pay for what AO3 does for free, but it's cheap and supports an indie developer, so if you use the website a lot, why not?
cool extension
A great addition to the ff experience - the 'read whole work' option is super convenient when you have a 100-chapter drabble fic, and the 'download fic' option frees me from having to download an entirely new software to get those sweet, sweet fics injected directly onto my phone in epub form.
I've been using fanfiction.net for many years and this extension makes the whole experience so much better. I love how it lets me download fics so I can read them on bus rides despite my very limited data plan. The "entire work" function makes it so much more convenient too. Fanfiction Ultimate works perfectly and I would highly recommend it to all avid fanfic readers!!
