The addon doesn't save trusted, untrusted and custom entries. Maybe the plugin stores information in non-persistent storage (which is cleared with any privacy-aware configuration).

This makes the plugin unusable, as re-allowing all services every single time is way more time consuming than just blocking scripts alltogether.

And even if you manage to save settings, they're not synched, so users who use two or more devices need to re-apply settings every time, on every. single. device.

The old version worked a whole lot better, it's a shame this level of quaity has not yet been achieved on the new WebExtension version.
