MV3keepAlive

MV3keepalive addresses the needs of extension devs struggling with the new Manifest V3 constraints. It will keep any other extension's service worker active requesting it. Service workers are known to die after 15 seconds when none of its event listeners are woken up and at best after 5 minutes. This can be used when the persistency of an MV3 extension is too expensive in terms of implementation or performance. Please install this extension and then modify your service worker and manifest.json files as indicated in our github repo at https://github.com/addeective/mv3keepAlive
