Question about Firefox 1.0

I know this is a VERY stupid question, but Im very uneasy when it comes to installing/updating software, and wanted to know if I needed to install my previous version of Firefox (I think its 0.8 ) before installing 1.0. I know its a stupid question but wasnt sure if it needed done. Thanks for all help. Xaq

 

The way I have always done it is by deleting the firefox folder in program files and then install the new version. You will retain all of your settings and skins and bookmarks

The key is to keep your profile , don't delete that!!

 

OK, I deleted the folder in program files and kept my profile folder. I installed 1.0, but 0.9 still shows up in add/remove programs. Should I try to remove 0.9 or will it not cuase any problems. All help appreciated.

When I deleted the program files folder for firefox and then reinstalled the newer version 1.0 This is what I have in add/remove only the one instance of firefox.

 

alright, I opened the registry and deleted keys concerning firefox 0.9 and left the 1.0 ones, and everything seems to b ok from here. Thanks everyone for the help.
