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

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!

Large data (file contents) is stored in IndexedDB, only settings and file meta data in localStorage.

For Scratch in Firefox:

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

Edit: Also Etoys, sadly.

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

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

Cool, one of the examples (etoys) crashed Safari (8.0.3) FTL JIT. :)

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