Re: [CentOS] mozilla and seamonkey not the same

How can I continue to use the old mozilla?

You will have to exclude seamonkey and mozilla from updates. This will affect your ability to install applications which require newer versions or are built against seamonkey.

Both for system updates and for new 4.4 installs.

This will only work for updates. There is no way for 4.4 installs. You'll have to uninstall the new stuff and install the old stuff, then exclude it in yum. This is not a good idea. There will not be security fixes for the old mozilla packages so you're running them at your own risk.

I need the -remote functionality to not open new windows.

File a bug upstream in RH's bugzilla. Beyond that, there's not much that you can do.
