same here, looks like the cert expired, not sure how to escalate

same here, please fix!

Sorry, everyone, I think you need to disable the extension temporarily until it is updated (if the certificate is part of the extension). Hopefully there will be an update soon.

Disabling Extension

You can view, disable, and often remove extensions on the Add-ons page. Either:

• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons
• type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading.

Find the extension on the list and click its slider switch to disable it.
