I have recently updated Noteboard. This update includes various improvements. You can visit Noteboard through noteboard.eligrey.com and noteboard.nfshost.com.

• Instead of using Mozilla’s non-standard storage interface, I changed the code to use the standard WhatWG Storage Interface. Using this interface lets Firefox 3.1+ manage the data set by going to Options -> Advanced -> Network -> Offline Storage.
• Ctrl+S now saves the text. I recommend you do Ctrl+Alt+S to not trigger the “Save As” dialog box. I accidentally used to push Ctrl+S all the time forgetting that it will autosave when I close the window and it couldn’t save in mid-edit. I can’t override the default Save As dialog box without having access privlaged scripts which are only for addons, ect.
• Alt+Ctrl+D deletes all the data stored by Noteboard on the domain it is currently on. Think of it as clearing your cookies if Noteboard actually set cookies. This is mostly needed as an alternative to using Firefox 3’s buggy offline storage management that doesn’t work most of the time.
• When you Ctrl+V paste, the text is autosaved.
• Will work on any browser that supports localStorage or globalStorage and will temporary store the data for browsers that only support sessionStorage

Update: I never mentioned this but the last version of Noteboard had a tiny update that never got a blog post about it because of the update being so small. The update allowed it to be served in data URIs opened through links or in iframes due to most browsers allowing data URIs to inherit the domain of the referrer. This means you can serve Noteboard 1.0.1 in data URIs now.
