Just because nobody asks you to do something doesn't mean it's not time to get rid of it. The person I live with just took the trash out without anyone telling them to, and if they hadn't, I would have.

Sometimes when something is old enough or broken enough or gets little enough use, it's better to trash and/or replace it with something new, rather than to keep trying to restore it to working condition.

TL;DR: Wikia staff are Marie Kondo and the chat extension does not spark joy.
