We started preventing links in summaries and eventually decided to be more aggressive against them, to avoid spam/malicious links (#15254)

Those add-ons already had links in summaries and should be cleaned up. We need to run some numbers to see if it makes sense to automate that or simply ask developers to fix the text themselves.

Anecdotally of course, but two of my add-ons are affected by this. These are auto-generated, which makes it feasible to parse/replace automatically.

View source code of Firefox add-ons and Chrome extensions (crx/nex/xpi) from <a href="http://addons.mozilla.org" rel="nofollow">addons.mozilla.org</a>, the Chrome Webstore and elsewhere, with CRX Viewer (crxviewer).

An efficient way to prevent Slack from replacing links with <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/b722ca95d5c185ef754582cdedd5c7e09925155cee456b493441c6b5592ad915/http%3A//slack-redir.net" rel="nofollow">slack-redir.net</a>, while still protecting privacy (against referrer leakage).

There is a significant number of add-ons impacted: 4.3k publicly listed extensions (and a lot more themes).

I think we should copy localized_string to localized_string_clean for affected summaries. This would leave the link if it was added before we started preventing their addition, but without the HTMLification, so it would simply render as plain text.
