Snapshots seem not to work for me. When I hit the snapshot button and then try to view the snapshot, a dialog box gives the following error:

The attached file could not be found.

It may have been moved or deleted outside of Zotero.

For what it's worth, I'm using Linux. I have noticed that the directories within ~/.mozilla/firefox/[profile]/zotero/storage are mode 644, which prevents me from viewing the directory. When I chmod the directory to 744, I can see that the directory is empty. Furthermore, I was trying to take a snapshot of this page, but any snapshot seems to fail.
