I updated my Firefox and it downloaded 1.5.0.10, not version 2.0.

Do I need to uninstall 1.5 and reinstall 2.0?

That strikes me as odd.

I can't imagine there would be anything wrong with un-installing 1.5, and re-installing 2.0.0.2.

Just to be safe, you may first want to visit the Firefox Web Forum, and ask there.

Doesn't the auto update feature only work on 2.0?

I'm running 2.0 and it hasn't updated autoamatically either...

Mozilla is keeping parallel versions of Firefox updated for the time being. Version 1.5.0 and Version 2.0.0 will both receive the security patch. However, after April 24, 2007, only version 2.0.0 will be updated. So you're set until then.
See the page linked below (BTW it hasn't yet been revised to show today's release).

you need to download the mozbackup utility and run it.
This will save all of your bookmarks, passwords, extensions, and all the other addons and stuff you've customized to your FF 1.5.x installation. http://mozbackup.jasnapaka.com/download.php

You can then donload FF 2.0.0.2 and install it as a new installation, and retain your 1.5 installation for the time, just to be safe.

Everything you saved with mozbackup SHOULD be automatically brought into the 2.0.0.2 installation with the new installation wizrd that comes with firefox 2.0.x
