Vista install noob questions

[Turtles]

Got a quick (hopefully) few questions.

1. How can I transfer my old firefox bookmarks from my old hard-drive on XP to firefox on my new hard-drive on vista. I've located the backup bookmark firefox files from my old HD but I don't know where to put them in vista. I've got firefox installed on vista.

Making a mess at explaining this I think but.

In XP, the bookmark backup files are at:
Documents & Settings > 'username' > application data > Mozilla > Firefox > Profiles > 'profile' > bookmark backups

In Vista, I don't even have a Documents & Settings and I don't have a scooby where to put the bookmark backup file. In firefox I can go to file > import but the only option I get is to import from IE.

2. Same as above except for addons this time. Where can I import them from and where to?

3. Do I want Windows Defender left on? I've got Avira running as well....

4. Is Windows Firewall fine or do I need to install an alternative. I'd been using Zonealarm on XP for a few years and thought it was great.

5. Transferred my Steam folder across from my old hard-drive and when I create a shortcut for Steam and try to launch it, I get this error:
Steam.exe (main exception): Unable to write to the current Steam application folder. Please move Steam to a folder where you have write privilages.


Help me please

Having problems with Mozilla Backup. It automatically recognises the firefox I have installed at the moment, but doesn't recognise the firefox on my other hard-drive. When I manually browse it, I cannot find any of the files the program says it needs.

EDIT: Added another problem to my list.

3. I'd leave Windows Defender on it doesn't scan that often neither does it seem to interfere with my AV (Kaspersky)

4. Windows Firewall is fine. If you're behind a router you're pretty much fine regardless.

Thanks for the advice

I think when I used it I just clicked on the backup file itself and it starts to work, I don't have Vista so I carn't help with that.

Yeah, i've had another shot but and it's just recognising the current profile I'm using (with nothing) and not recognising the FF I had on my old hard-drive. When I manually browse using MozBackup I cannot find the file it needs to backup (.pkv/.zip) or something.
