Enable/Disable/Whitelist Not Working

[smashedr]

This extension is preventing Grafana from loading even when toggling the extension off for the site, verifying it is in the whitelist, and all whitelist boxes, including All APIs, are checked.

Expected Behaviour

I would expect Grafana to load after disabling the extension for that site.

Current Behaviour

This error is throw in the console and the site fails to load: Uncaught TypeError: `target` argument of Reflect.getPrototypeOf must be an object, got null

Possible Solution

The only solution is to disable the extension in the addon manager.

Steps to Reproduce (for bugs)

1. Install the addon
2. Attempt to load Grafana
3. Disable the addon for the site
4. Refresh the page

Context

Makes the addon unusable since it must be completely disabled to load Grafana.

Yes, it is a known regression that affects Grafana and other sites (#705 #707 #709 #715). @kkapsner already started working on it, but unfortunately wasn't able to publish a fixed version yet.

Following for the same issue

[solonovamax]

this issue, quite annoyingly, occurs even if canvas blocker is set to "allow everything"

[kkapsner]

Close as a duplicate from #705

I can confirm that the whitelist isn't working at all.

Tried individual IPs and even netmasks - nothing seems to work. The issue is certainly with CanvasBlocker as when you disable it, Grafana works fine.

[kkapsner]

The next version that solves the issue is in the verification by Mozilla. In the meantime you can use the latest beta version (make sure to disable the normal version as only one of them should run an the same time).

This is great - I've been suffering through this for 6+ months now, WITH GRAFANA, and I finally went through the troubleshooting steps of disabling extensions in turn, zeroing in on Canvasblocker, etc. I come here to file a bug, search, and... not even an hour beforehand, I learn there's a fix in the works haha.

Following, so I can get notified when the Mozilla verification is in flight. In the meantime, I've been using Grafana in Private Mode (where CanvasBlocker is not enabled) with no issues.

Do we have a rough ETA on when the latest version will be verified by Mozilla?

[kkapsner]

No - I have no ETA.

[knaggsy2000]

Using grafana in recent days for me - hasn't produced the same.

Maybe something has happened outside of grafana?
