I can't open .XPI file on my MAC
I am trying to install import-export tool but when I download it and double-click on it I am getting the following message: There is no application set to open the document. Search the App Store for an application that can open this document, or choose an existing application on your computer. When I search App Store I can't find any app to open the XPI file.
Does anybody know a solution?
Thanks in advance!

Open Tools/Add-ons/Extensions, click the gear icon next to Search, 'Install add-on from file...', select the xpi.
