The extension requires access to the internal storage (indexedDB). If the "always use private browsing" mode is on or "accept cookies from websites" is off, Firefox prevents extensions from using indexedDB, and the extension will not work. Firefox 59 will fix this. This is not fixed yet (2019-05-26) and tracked at Bug 1427986.

If your browser is affected, you can customize the settings and create an exception for this extension:

Settings → Privacy and Security → History

Change "Firefox will..." to "Use custom settings for history".

Disable "Always use private browsing mode". Uncheck "Remember ... history" if you want, and there is not much difference between these options and "Always use private browsing mode". image

In another tab, open about:debugging#addons, find this extension, right click "Manifest URL", and copy the link. image

Then return to the settings tab, click the "Exceptions" button after "Accept cookies from websites" (the checkbox does not need to be checked), paste the link into the exception dialog, and click "Allow", "Save changes". image

Restart.
