just FYI, many , if not most extensions will work in 3.2
some will also work in 3.3
however, the quickest way to find out is to install it. if it doesn't work, simply disable it and uninstall it.
or, you can disable it and then ask the author how to make it 3.3 compatible.
it would be rare that installing and enabling an extension would cause any problems that disabling it and uninstalling it won't solver instantly.
so, like my software engineer mother taught me; " Make a backup and then push the button and see what happens."
