What is the 2007 Microsoft Office Plugin for Netscape Navigator?

"Nobody knows.

Google doesn't know. There is a pretty good article about the previous version on ProcessList.

But the current version? No details. This page is #5 on the results!
Microsoft doesn't know. Use the inline ""Bing"" interface at www.microsoft.com

At some point in the future, I would expect the Mozilla Plugin Checker will at least display the current version, but I think that is all you can determine for now, without calling Microsoft and getting the paid-for-support answer."

This plugin should allow you to view, alter, and save excel workbooks online (such as spreadsheets hosted on docs.google.com)
