I installed this extension on FF that came default with my Xandros install. Last night I was attempting to make some changes in the "preferences" section of it, and there was no ok or cancel buttons to save changes. Checked the same thing here at work and obviously those buttons are there so should exist on the one at home I assume. Just don't know if the issue is because it's on the pre-packaged FF v.1.0.2 from Xandros.
Any ideas or just reinstall the extension and see what happens?
