Also, what can I do when FFF keeps reporting it can't find a page in the cache that I definitely loaded in the browser? I hope ffnet hasn't started using a cachebuster...

EDIT: Opening the page with inspector shows the code is 304, which indicates that it's cached—page source shows that login.php uses a cachebuster (likely in response to that near-security breach) but not seeing it anywhere else.

I've tried both Vivaldi and Waterfox caches. Weirdly, with Waterfox it instead says that it can't recognize the cache even though I put in the exact folder.

EDIT: I figured out the problem. The chapter I wanted was /s/xxxxxxxx/51/ but using update from the menu instead of URL looked for /s/xxxxxxxx/1/.
