Endless scroll.
A Tampermonkey userscript that adds optional endless scrolling to paginated gallery listing pages on nhentai.net, with dropdown page control. It avoids affecting doujin pages (/g/...) entirely and includes quality-of-life improvements like lazy image fixing and arrow key protection. (Other extension other than Tampermonkey might work, if not please give us feedback)
PLEASE NOTE: In ♾️ Endless mode, you must scroll to the bottom twice (bounce up and down) to load the next page. This prevents accidental continuous loading every time you scroll.

FEATURES:
1. The script automatically disables itself on:
-https://nhentai.net/g
-https://nhentai.net/g/123456
Why? To avoid breaking individual doujin reader pages.
2. Endless Page Loading
Uses Tampermonkey's GM_xmlhttpRequest to fetch next gallery listing pages
Parses and extracts the #content block, appending to the current page
Prevents duplicates using lastUrl
Prevents overloads using isLoading, reachedEnd, and scroll confirmation
3. Bottom Detection with Double-Scroll Confirmation
Forces user to scroll to bottom twice before loading more
Prevents accidental infinite loading (nice UX move)
4. Dropdown Control with 1–5 Page & Infinite Mode
Lets users choose how many extra pages to load
If 1–5 selected: loads them immediately
If ♾️ (Infinity) selected: enables scroll-based auto-loading
5. Movable Dropdown UI
Users can drag the dropdown anywhere on the screen for convenience
Styled to match nhentai’s aesthetic without being intrusive
Additional Polish:
Fully modular functions (like fixLazyImages, loadNextPage, etc.)
container.innerHTML = '' clears old content on dropdown change
Defensive checks for #content, .gallery, etc.
console.log for status updates (great for debugging)
@connect-src nhentai.net enables cross-origin fetches
