Waterloo University 1 519 888-4567, tells me in no uncertain terms that as of this moment, Firefox 3.6 is the only version that does not cause problems in dealing with distance education students. I have already experienced one such problem and I am desparate... as long as this situation exists... to keep from upgrading my 3.6. Your system refuses to pay any attention to my need, at present, to NOT UPGRADE. It is now planning to force this upgrade on my computer.
