Dynamic Domain Redirector od Sajeeva SA

Dynamic Domain Redirector allows you to automatically redirect one domain to another while keeping the rest of the URL intact. This is useful when websites change their domain name or move to a different TLD, and you still want your bookmarks or old links to work without updating them manually.

Users can configure the source and target domains via the extension’s Options page, which is accessible through the Firefox Add-ons Manager. The extension also provides a toolbar button that lets you instantly update all open tabs from the old domain to the new one.
