This patched version of the addon is no longer necessary - the fixes included in this patch are now a part of the main Unboxer addon, so please download that instead! Shoutout to Masteroshi430 for taking charge of the addon and getting this fix merged in. And of course, a big thank you to silvereyes for creating the addon in the first place! 
The amazing Unboxer addon by silvereyes with a minor patch to automatically open Tales of Tribute reward coffers. This patch will be archived if/when the main addon is updated with this functionality
The translations for the new Tribute menu item may not be 100% accurate, but I did the best I could with 20 minutes of work
Note that you should only have one version of the addon installed at a time. You should remove the existing Unboxer addon before installing this patched version.
