I think we've discussed this before, ni'ing myself to find the dupe

Ah I was thinking about bug 1308640 which fixed it for fetch. It looks like this is opening an iframe to gmail though?

As of bug 1345158, the extensions can now check to see if trackingProtectionMode is enabled and at least raise a warning to the user as documented at: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/privacy/websites

Adding https://mail.google.com/* to permissions gets past the never loading issue, but it still doesn't get messages as it does with TP off. I don't see any messages about anything being blocked once I've done that, but it seems that something is. Maybe François has some idea why TP might block something, but no logging appears about it.

Further info. appcache is used by the addon, and there are failures around that. however, those failures happen with tp off, and the extension appears to work in that case. I wonder if TP does anything around appcache (e.g. loading something appcached that might not be in permissions).

I don't have any ideas about why it's happening, but if it's happening, it's probably a bug :) If you want to confirm that TP is the one blocking the resource, you can enable the MOZ_LOG debugging: MOZ_LOG="UrlClassifierDbService:5,nsChannelClassifier:5" (see https://wiki.mozilla.org/Security/Tracking_protection#QA) (In reply to Shane Caraveo (:mixedpuppy) from comment #7) > Further info. appcache is used by the addon, and there are failures around > that. however, those failures happen with tp off, and the extension appears > to work in that case. I wonder if TP does anything around appcache (e.g. > loading something appcached that might not be in permissions). Appcache is not currently covered by tracking protection (see bug 1262339).

This problem is still present on latest Nightly builds.
