@Omini yes, I just tried this way too, it still seems to cut-off at 1,000,000 bytes, so it wasn't related to breaking due to content etc, it still seems to be a data length / quota memory problem
@austzxy If this error occurs, then you are definitely using some action to work with the browser without using the browser itself.
@jd-ofm that's on browser settings > addons just put in your addon ID, that's it
