This issue reports that Nightmare does not load NPAPI plugins, which are needed for some login flows. NPAPI is a deprecated plugin architecture, and modern browsers including Electron/Chromium have dropped support. The repository is archived (segment boneyard), so the issue may be irrelevant. To proceed, a contributor should first confirm if the repo is still maintained, then check if NPAPI was ever supported in Electron. Look at the codebase for plugin loading in lib/nightmare.js or similar. Since there is no detailed reproduction, the contributor should attempt to create a minimal test case using a known NPAPI plugin. However, given the deprecation, this is likely not a feasible fix.
