pywalfox: Error: Native application tried to send a message of 1634038339 bytes, which exceeds the limit of 1048576 bytes

Overview

I’m getting this error in the debug output of the Firefox plug-in itself and a couple of related errors, but I think they are caused by the original error, but I’ll include them anyway. I have gone through the troubleshooting section in the README.md and everything there seems to be correct on my system.

Errors
