Any idea what the examples are trying to store offline? And where in the code that is?

Here, let me do the equivilant of LMGTFY: https://github.com/bertfreudenberg/SqueakJS/search?utf8=%E2%...

Looks like it's storing settings, images, and files created by said images.

Reminder that Squeak is a full VM and naturally has file-io abstractions which must be implemented.

Right, brainfart and I couldn't remember the name of that API. Thanks!

Impressive. Did you realize that after loading doesn't even need internet anymore?

For Scratch in Firefox:

  UnknownError
  "Error opening database: undefined" vm.js:358

:(

Edit: Also Etoys, sadly.

Yep. I reported that a while ago, but it's not fixed yet: https://bugs.webkit.org/show_bug.cgi?id=136803

Works for me in Firefox 34.0.5, default settings. Would be great if you could post instructions on how to reproduce at https://github.com/bertfreudenberg/SqueakJS/issues
