See README.md.

In a short, you're downloading a gallery that's too large and the browser cannot handle it. That's the limit of your browser (and your system if you don't have too much RAM).

There should be a warning popup before you downloading a gallery that's larger than 300 MB, and for best practice, never download a gallery larger than 500 MB.

For large gallery I'd recommend using torrents for free if available, or offical archiver by spending a few GPs, or tools that doesn't rely on browser like gallery-dl.

I'd say Firefox is somehow tricky. Around 9 years ago when the script comes out, sometimes Firefox will pass but sometimes it throws out of memory error, and a possible way is using browser's advanced GC function, where you can still find it here.

But I checked your case just now, it seems that the 2 GB hard limit is the same as Chrome (or say it would probably be Chrome copied Firefox, since Chrome only have 500 MB years ago). I'm not sure if it's a standard, but at least it's a browser side limit.

At that time, there's a way to bypass such limit is FileSystem API, which should be a standard but removed years ago, and now becomes Chrome-only API. So if you're using browsers not based on Chromium, you're out of luck. There're new ways to fix it like the tricky Services Worker + Streams (#226), or the Chrome-only-for-now File System Access API, but for now I've no plan to implement them.

Duplicated with #252 .
