So while I'm still waiting on NoScript to get an update which is actually forthcoming (possibly tomorrow, but within about a week from what I gather), I took a look around to see which of my other add-ons were updated.

Other than a couple that were useful but ultimately not that important, and a couple I can do without until they get updated eventually, I managed to find that most of my Legacy extensions do have updated versions out. Namely, Video DownloadHelper and Greasemonkey, both extensions I thought would die with Firefox 57 out. That said, I wouldn't have known if I hadn't looked at the add-ons site as near as I can tell, while they still say "Legacy" in my Add-ons tab, they do have separate releases on the add-ons site specifically for Firefox 57 which are incompatible with my current browser and I'll probably have to install them again when I do update.* Assuming that is the case, you might find a decent chunk of that 70% already ready and you just have to take some extra steps to get them working again.

Overall, I am optimistic, lots of people have lots of nice things to say about 57 and the extensions situation is not looking nearly the sort of bad I was first expecting. I'm sure I've had more painful wait periods for my extensions going back almost a decade ago as it seems I really am waiting on just one and that one is coming shortly. Even those extensions which are now unsupported actually seem to have decent replacements and I've switched them over already.

* Note, this portion is entirely speculative, refer back to my commentary on waiting till an updated NoScript comes out before I actually install Firefox 57. It's possible they would just update once I do upgrade to 57 rendering my subsequent speculation entirely wrong.

Greasemonkey will be updated from legacy to the compatible one automatically, no user intervention needed. I assume this holds true for all such extensions.
