see <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/352659e59afc32840ccc941e2a056b5af8884448cb898f74c3a5cc062a2282bc/https%3A//github.com/turistu/odds-n-ends/blob/main/firefox/pastejack.md%23workaround" rel="nofollow">https://github.com/turistu/odds-n-ends/blob/main/firefox/pastejack.md#workaround</a>

WARNING: this will break a lot of sites, including discussions in github.

OF COURSE, this does NOT access any of your data on any website. It's just that firefox's permissions are totally retarded. This temporary kludge may be broken or pointless, but one thing it's certainly not: it's not "accessing" any of your data.
