OpenItOnline for Firefox opens Office, image files with web apps
By now, many of you are probably using web-based office suites like Zoho, Google Docs, or Thinkfree as your primary office applications. If you do and you're a Firefox user as well, you'll probably love the OpenIT Online addon.
I mentioned it previously in my list of 14 extremely useful addons, but it's been updated quite a bit since then.
When you install the plugin, the configuration wizard will help you create file associations. You're not limited to one suite, either. If you'd rather open spreadsheets with Zoho and documents with Thinkfree, OpenIT can handle that. Zoho viewer is also supported and is a nice, fast way to view files you don't need to edit.
OpenIT adds two context menu entries (which you can see in the screenshot above): one to open a file with your default viewer/editor and a submenu that provides access to all available options.
This is a great extension to add to your portable Firefox install. It's an excellent way to make sure you can open a wide array of documents on any computer.
