Adds a button to open every gallery on an E-Hentai / ExHentai listing page in background tabs, with a delay. Works in all view modes; click the button again to pause or resume.
Adds an **Open Galleries** button to E-Hentai / ExHentai listing pages (search
results, favorites, uploader pages, etc.) that opens every gallery on the page in
background tabs, one per second.
**Features**
- Works in all list view modes (Minimal, Compact, Extended, Thumbnail).
- De-duplicates so each gallery opens once.
- Asks for confirmation before opening more than 30 tabs.
- Click the button again to pause, and once more to resume.
**Note**
- Opening many galleries quickly can trip E-Hentai's rate limits (509 / image limit).
Use a reasonable page size and don't spam it.
