Have just upgraded to version 1.0.4 ( from 1.0.3 )via Mozilla site click here . From Firebird browser select Tools, Advanced, Software Update, Check Now this will take you to the downlaod which will be installed for you. I have always done it this way and have never had to remove the former version at all. I had to reset my Home Page but everything else seems to be the same with no problems.
SEASHANTY--I have never needed to uninstall the old version first...all the updated versions from the Beta to today's have installed over the top of the older versions without problem.Just updated via the Firefox tools route like Nuts did.If I get a problem with this way of updating THEN I will uninstall and put the newer version on from scratch....until then I am not going to make unnecessary work for myself.But I'm not going to Suggest anyone disreguards the proper instructions either..you do things whichever way works for you.I'll put money on the fact that those of us who meddle and take shortcuts are more practised at full system reinstalls than those who follow the instructions, lol.
