Heads up: If you're downloading a larger book, rely on the progress bar in the Download button on the IA webpage, rather than the download menu in Firefox itself. Even then, it took the add-on a few tries to successfully download the 500-page book I was after, with multiple failed attempts retrieving an incomplete or unreadable PDF, so you might have to be persistent.

Extension reports"TypeError: NetworkError when attempting to fetch resource..
Please contact the developer." It worked fine with previous Firefox versions. Since Firefox was updated to 134 it constantly reports the error above.

The Chrome plugin works flawlessly, but this Firefox 'port' at first wouldn't, giving me a Blocked error message when I clicked on download. It apparently has something to do with Cross Origin restrictions.

I tried several things, including Private mode, but in the end the only thing that worked for me (in standard mode too) was the "Allow CORS: Access-Control-Allow-Origin" by Muyor plugin. Disable uBlock Origin or whatever for Archive.org just in case.

Please add this tip to your plugins description. So far 2 succcessful artbook PDF downloads at Max Resolution. And thank you for creating this. I wish there was a way to grab the original Jp2s instead of Jpg, but I haven't found one yet (not a coder).

Extension works after giving full permissions, but I'm struggling to utilize this extension since even a small book ends up being almost a half a gigabyte. Every page is over 20000x20000 resolution and I can't convert anything without it taking over a day.
