It's now possible to name a package in a ubuntuupdates.org URL and get directly to the page for the latest version of this package. Just append its name to http://www.ubuntuupdates.org/. For example, to get directly to the package page for the latest version of Firefox, use http://www.ubuntupdates.org/firefox
Not sure you want exactly the latest version of that package? Go to the search page instead: just insert "pm/" before the package name. That displays the full list of versions of this package in all repositories: http://www.ubuntupdates.org/pm/firefox.
To summarize,
- Link to package: http://www.ubuntuupdates.org/<package name>
- Link to list of versions: http://www.ubuntuupdates.org/pm/<package name>
