In Krusader, I can enter a .zip (or .tar etc.) file as if it were a directory, and view/copy/etc. the files in the archive.
How can I tell Krusader to do the same for .xpi files (which are really just zip files with a .xpi extension)?
Currently, pressing enter or double-clicking an .xpi launches firefox, which prompts for the install of the extension. This is probably due to
(I'm using Ubuntu 16.04 and Krusader 2.4.0-beta3)
