Additional Information

Was looking into what was going on with bluesky that I could see, that would be causing my laptop to heat up. While it should be noted the error increased with frequency the longer the debugger was up, it had occurred several times before I had opened said debugger. It was already in the error list upon immediate opening, and ublock had been tracking blocked links for a bit before hand.

According to Ublock Origin, this is due to privacy filters, implying the event request in question is some sort of analytics thing. Not a reason to turn off Ublock (quite the opposite actually), nor is it a reason for filters to be changed. Does raise questions as to what this event request is, and why it would be run.
