Mozilla recently release version 10 of Firefox. Many of us stayed at version 3.6 while some of the more glaring issues were resolved with version 7 (and then version 8). We are new Nefsis customers (in our free trial right now) and are not really ready to add a new browser to our mix. However, I do have to ask if you know of any compatibility (or other) issues with Nefsis and this new release. (One thing that may be an issue is this add-on now works differently and may not do what you need it to: https://addons.mozilla.org/en-US/firefox/addon/15003 )

The Nefsis QA team tested Firefox 10.0 and did not find any technical problems with it.
