- by Firefox user 12827221, 5 years agoRated 3 out of 5Since there is no description, i pulled it from the inspiring firefox bug discussion (https://bugzilla.mozilla.org/show_bug.cgi?id=8648#c45)
The extension watches for redirects that the browser follows. If they have status code 301 (ie, permanent), it'll search all bookmarks for the old URL, and update them with the new URL.
There's no current handling for 404s or any other status codes. Also, HSTS upgrades aren't detected by the extension, as these don't generate a 301 from the server. (They happen client side.)
- by Martin Ueding, 5 years agoRated 3 out of 5I have tried this add-on and it works reliably. It seems to remove the bookmark and create a new one, either way: The tags get removed after visiting the site. This can be destructive if lots of tags are used.
Developer responseposted 4 years agoThe API the add-on uses doesn't have access to the tags nor description. The way this add-on uses the API it only changes the URL, and doesn't delete/recreate the bookmark.
[Update] I've looked into this and it appears to be a bug in Firefox itself. I've raised a bug report to get this fixed.
