Question

Values set in local storage in background.html could not be accessed in javascripts loaded using content_script entry of manifest.json and vice versa. is this the default function of localstorage ? or am i missing something.

For example if i storing a value from myscript.js which is injected for each page load that could be accessible within myscript.js when i tried to access that in background.html it says undefined.

The same happens when i set a localstorage in background.html and try to accesss in myscript.js i couldn’t were as it can be accessed in the page or script where it has been created or set.

Is this the default behavior or am in missing something?

Answer 1

This is the default behaviour.

Content scripts injected into normal webpages can’t access your extension’s local storage.

And your extension’s manifest can’t access local storage, either.
