As the title says. I found a previous post addressing this issue: https://www.reddit.com/r/LibreWolf/comm ... orking_on/
I also tried to contact contact the author of the extension (Kai Uwe Broulik <kde@prviat.broulik.de>) but it seems like his email doesn't exist or his email provider automatically rejects me. Hopefully I can raise some awareness about this issue.
