Don't slack-redir links Autor: Rob W

Prevents Slack from replacing external links with "slack-redir.net", and prevent referrer leakage, so that your Slack URL does not end up in the access logs of the linked website.

This extension aims to do that in the most efficient way possible. There are other extensions with similar functionality, but they either work by responding to changes in the whole document (using MutationObserver, which is costly) or by fixing up links upon click (which may fail if the extension runs too early).

None of the extension that I reviewed had precautions against referrer leakage. Since Slack hides the referrer by default, this shouldn't be a problem. But an admin can change this ( https://slack.com/intl/en-gb/help/articles/204399413 ), which results in unwanted referrer leakage.
