Restoring Data From Accidently Removed Extension

I-Firefox Sync data

I mistakenly removed an important extension (LinkLocker, which I wrote, actually) from my synced work computer, not realizing it would be removed from my home laptop as well.

Unfortunately, I saved a significant amount of data in that extension's storage and, after reinstalling it, can't seem to recover it.

Is this data lost forever or is there some place I can look to find it?

Hi, you could look in your profile directory if something is still there? about:profiles tells you in what directory to look. Good luck!

When you uninstall an extension then normally its data stored in indexedDB (storage/default) is cleared/removed because if you would reinstall the extension then it will get a new UUID as stored in extensions.webextensions.uuids. There are prefs in about:config to prevent/affect this, but this won't help you with this case, only for future cases.

These two prefs in about:config determine what happens if you uninstall and reinstall an extension.

  • extensions.webextensions.keepUuidOnUninstall
