Mozilla has just launched another web-app framework. Prism, kinda like Adobe AIR and Microsoft Silverlight, allows you to take websites with you to the Desktop.
It works this way: first you install Mozilla Prism. Then you start the app and type in the URL of the website you want to take with you to the desktop. Whooptedoo and you have a “standalone application”. Really, it’s like a dedicated Firefox for your application: no toolbars, just the website.
It works. It works well. I like that I can
ALT+Tab to Gmail instead of previously having it as an open tab in Firefox.
So far, while you can take websites to the desktop, you can’t take them offline. To my knowledge, there’s no local storage going on, but I’m sure if this is a hit, some offline functionality will arrive, even if it’s just a mashup of Google Gears.
For now, Prism is interesting. It works as advertised and does what it says on the label. Personally, I’ve got desktop versions of Gmail and Google Calendar handy.
