Enable/Disable/Whitelist Not Working #718

Open smashedr opened 3 months ago

smashedr commented 3 months ago

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 commented 1 month ago

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