Description

If the Library Extension’s settings page shows a banner that reads “Lost connection to the extension. Reload this page to continue.” with a Reload button, here’s what’s going on and how to fix it.

What it means

This banner appears when the settings page loses its connection to the rest of the Extension and can’t recover on its own. The most common cause is that the Extension updated, or was reloaded, while the settings page was still open in a tab.

How to fix it

Click the Reload button in the banner, or simply reload the page yourself. Nothing is lost. All of your settings are saved, and the page will pick up right where you left off.

Is this different from results not showing up?

Yes. This banner is specific: it tells you exactly what happened and exactly what to do about it. If instead you’re finding that results simply aren’t appearing on book pages, that’s a separate issue. See our Frequently Asked Questions page for help with that.

If you’ve seen this before without a message

Before version 2026.810.1, this situation didn’t show any message at all, and the settings page would just appear to hang. If that happened to you in the past, this banner is the fix: the page now tells you what’s wrong and lets you recover with one click.
