type in the manifest link (chrome-extension://adkcpkpghahmbopkjchobieckeoaoeem/manifest.json). don't press enter. then, start dragging the tab out of the window, and while you hold it, press enter. it will not close.
open main.js with the same instructions above (chrome-extension://adkcpkpghahmbopkjchobieckeoaoeem/main.js). once you press enter while dragging the tab, it will go to its normal place. start dragging it again as fast as possible while it loads. keep trying until it works.
print main.js. press Ctrl+P, then click "more options". set margins and scale to custom, and set scale to 200. make the margins (blue dotted lines in the preview) as small as possible to make as many pages as possible. wait for the preview to load, then do the next step. it should show about 200,000 pages on the top-right when done.
reload the extension. open chrome://extensions?id=adkcpkpghahmbopkjchobieckeoaoeem in a new tab. right-click the main.js tab and click "duplicate". Then, click the "allow access to file urls" switch once. this reloads the extension. the extension is now hanging. you can now close all of the required tabs and enjoy!
