With my decade-long experience as a full-stack developer, I can proficiently handle your Chrome extension upgrade from Manifest V2 to V3. My understanding of different web development technologies notably includes ReactJs, Nextjs, Strapi, NodeJs, Vue js, AngularJs, MongoDB, ExpressJs, PHP, Laravel, and many more that underline my solid comprehension of JavaScript. All these skills are boosters in handling the APP_ID_OR_ORIGIN_NOT_MATCH error you mentioned.
Transitioning from one manifest version to another can be complex but that's where I excel. I have worked on numerous extension migrations before enabling me to anticipate and troubleshoot potential issues effectively and efficiently. With my workflow, the functionality of your extension will remain intact as we focus solely on getting it up and running without errors.
Lastly, one of the crucial components for this project would be the Auth dashboard setup for a seamless transition between manifest versions. My expertise with database management (MySQL, JSON, Mongo) and authentication systems allows me to not just deploy but optimize the dashboard according to your exact requirements. I'm keen to ensure stringent deadline management without any compromise in the quality of my work. Let's transform your Chrome extension for a better browsing experience!
