I'd really love to hear if you have some ideas about uncluttering it. We've iterated lots of versions till we got to this state.

The canvas drawing confusion seems to be quite spread. We'll definitely have to add something about it.

Oh wow, that's but is nasty.

Let me explain why you got that, you'll find it hard to believe, I promise :)

We use an iframe to upload the tiles directly to s3 and s3 redirects back to the site on success. However, in firefox 3.6, if you refresh the page with such an iframe present, it'll reload the last iframe src, even if the src is now about:blank, because you've just reloaded the page. So, in effect it'll hit the "tile just uploaded" page again. Which is a completely stupid thing to do.

Therefore, when we receive one of the s3 uploads, we also redirect to a page which expresses how we feel.

You might ask yourself why you saw it at sign out. Because we're idiots and the code that remembers the last page you saw to be able to redirect correctly after sign in/sign out remembers this request.

So, I'm guessing that you uploaded a tile, then hit signout immediately, amirighte?




Will go back and look over usability stuff again, but just quickly yeah id just uploaded then logged out (In latest stable chrome btw, not ff).


Yup, FF is just the root cause. We didn't do any browser sniffing for the fix.
