I want to download some .nupkg files using my browser
In nuget.org, there are no links to the .nupkg file
The URLs are typically in the format:
http://nuget.org/api/v2/package/PACKAGE_ID/VERSION
For example, for WebActivator:
http://nuget.org/api/v2/package/Microsoft.Web.Infrastructure/1.0.0.0
If you just want the latest version of the package, leave out the version number:
http://nuget.org/api/v2/package/Microsoft.Web.Infrastructure/
