Rated 5 out of 5 stars

What a great add-on! I've been waiting for this one, and it works exactly as advertised. At my job, the engineers all use Visio, but we're too cheap to buy licenses for us marketing guys. Now I don't have to ask a colleague to print emailed files for me. I can view them right in Firefox. Perfect! Now can you make it open files from my computer? rev two? That would be awesome.

This review is for a previous version of the add-on (1.0.1-signed.1-signed).
