Worked on the mozilla/web-ext repository to enhance the Firefox extension signing process by delivering a focused documentation update. Used JavaScript and technical writing skills to clarify how the sign command submits extensions to Mozilla Add-ons (AMO) for signing, addressing common user confusion around the installation flow. The update provided clear, customer-facing guidance that improves onboarding and reduces support requests related to extension signing and installation reliability. The work was implemented as a consolidated documentation change, emphasizing maintainability and accuracy. This contribution demonstrates attention to user experience and process transparency, with a targeted impact on developer documentation rather than code or bug fixes.
