XPI Inspector Installation

Purpose and scope: The tool verifies the installation process for the XPI inspector extension in browser environments. It targets developers, QA engineers, security teams, and compliance auditors who need deterministic setup checks, reproducible test runs, and auditable installation records. By focusing on the XPI inspector workflow, it reduces ambiguity in prerequisites and ensures that each step aligns with that extension’s manifest and permissions.
Core logic & features: Required features include manifest parsing, version and permission checks, and a step-by-step validation sequence that mirrors real installation. Optional/advanced features include dependency graph analysis, dry-run simulation, cross-browser compatibility hints, and exportable reports in JSON or CSV. The tool enforces strict rules: manifest_version, name, version, and required_permissions must be present; optional fields are flagged if inconsistent.
How it works conceptually: Input is processed through a rule-based validator. It checks prerequisites such as browser compatibility, profile state, and signature or integrity signals where available. Results categorize issues as errors or warnings, attach remediation suggestions, and provide a reproducible checklist for engineers to follow during integration testing.
Use cases and differentiators: The solution supports offline validation, reproducible runouts, and a domain-focused audit trail for XPI installations. It benefits build pipelines, security teams, and compliance reviews by delivering objective, actionable insights and exportable artifacts that document each installation decision.
