Presumably, some entry in your sources list wants to upgrade libnspr4 to 1.7.3-5, which breaks mozilla-browser, since it requires the exact version 1.7.3-1ubuntu1. You can hold ('=' in aptitude) libnspr4 to 1.7.3-1ubuntu1, or remove the offending entry from your sources.list. Be aware if you hold it, that it will stay held until you manually select it to be updated. Holding it may prevent other packages from installing, if they require > 1.7.3-1.

Reading a little more closely, you already have 1.7.3-5 installed, which means that you can't install a package (like mozilla-browser) that depends on a version < 1.7.3-5. You can downgrade it, and possibly break other packages, or install a version of mozilla-browser that requires 1.7.3-5 of nspr. I'm not sure which repository gave you 1.7.3-5 nspr, but it wasn't warty or hoary.
