Public bug reported: Suppose in Firefox you click a link to a .deb package. A dialog named "Opening [filename].deb" opens. If you select "Open with", then the .deb file is downloaded, placed in /tmp/mozilla_[username]0/ directory, then Software Install (as named in the Firefox dialog) is started on that .deb file.
Next, Software Install loads and fails with "Failed to install file: not supported". If on the other hand, in Firefox's "Opening [filename].deb" dialog, if I select "Save File" instead, the .deb file ends up in the user's Downloads directory. Software Install works fine with the package there. I don't want to get too much into solutioning or "why". The main point of this bug is that I should not get a weird error just because I selected "Open with" instead of "Save File". This happens with a vanilla install of Ubuntu, with nothing else installed, so the product isn't working in an intuitive way.
