Good replacement on FF Mac for the broken Acrobat Plugin - No print option though Rated 4 out of 5 stars
Love the plugin. Works as designed and good replacement on the Mac OS X platform since the Acrobat Plugin does not work consistently. The only negative is that it does not have a print option in it's toolbar, forcing the user to download the document if they want to print it.
If you are on Mac OS X (current version) with Firefox (ESR or regular version), this is a must have!
