If your browser extension isn’t saving data between sessions, here’s what’s going on and how to fix it.
The issue happens because the extension uses a service worker (not a background page). Without the service worker cache enabled, the data won’t stick.
Here’s how to sort it out ⬇️
Step 1: check for a service worker
- Launch Mimic
- Open the “Manage extension” menu
- Turn on Developer mode
- Scroll to “Inspect views” and look for “service worker” under the extension details
If you see this item, look at the solution below. If there's nothing like it, our support team will be glad to investigate the issue further for you!
Step 2: enable service worker cache
- Navigate to “Profile settings” → “Advanced” → “Storage options”
- Disable “Service worker cache” and click “Update profile”
And that’s it – from now on, the extension data should be saving! 😊
