chrome.storage.sync undefined?

Question

I\'m trying to use chrome storage in an extension, via a content_script, but I keep failing on

Uncaught TypeError: Cannot read property \'sync\' of undefine

If someone was facing this issue on Firefox, please note, that it is not supported yet:

https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/storage#Chrome_incompatibilities

For my purposes it was sufficient to replace chrome.storage.sync by chrome.storage.local.

Regarding the Firefox implementation state it might be worth to look also here from time to time:
