Has started to suddenly break a lot of websites, even while I have done no configuration changes in years. What's interesting that sites are broken even after disabling CanvasBlocker on a specific website (using the icon in the extension menu), only working once the entire extension is disabled. An example is a Grafana instance on the local network that I thought was a server-side issue, but was caused by CanvasBlocker (even while it was disabled for the domain).
