What the Check Links Extension for Thunderbird Does

Check Links is a Thunderbird extension from AE Creations that reviews the web addresses of all links in a draft email message. It is aimed at people who write emails containing multiple hyperlinks and want to verify those addresses before the message is sent. The extension works inside Thunderbird, Mozilla's desktop email client, and is listed on the AE Creations site alongside the company's Firefox tools.

What the extension checks

According to the AE Creations site, Check Links "review[s] the web addresses of all links in a draft message." In practical terms, that means the extension looks at the links already present in the email you are composing and surfaces their addresses so you can inspect them.

The site's description does not go beyond that scope. It does not state that Check Links tests whether a link is reachable, scans for malicious destinations, or validates formatting. Treat it as a link-address review tool rather than a security scanner unless the extension's own documentation says otherwise.

When it is useful

Check Links fits situations where a wrong or mismatched URL would be costly or embarrassing. For example, if you are sending a newsletter draft with a dozen product links, or a message to a client that points to a shared document, the extension lets you look over every address in one pass instead of hovering each link individually.

It is less relevant for short replies with no links, or for messages where the only link is one you just pasted and already know.

Where it sits in the AE Creations lineup

AE Creations publishes extensions for both Firefox and Thunderbird. The site lists:

Check Links is the only Thunderbird-only tool in that group, which makes it the one to look at if your work happens mainly in email rather than the browser.

How to evaluate it before installing

The AE Creations homepage gives only a one-line summary and a "Learn More" link, so the details you need for a decision sit on the extension's own page and in Thunderbird's add-on listings. Before installing, check the extension's page for its current version, the Thunderbird versions it supports, and any release notes. The site's blog is also worth a look: recent posts there cover beta releases and bug fixes for other AE Creations products, which shows the developer posts update news publicly. As of the site's latest news items, no Check Links release note appears among the recent posts, so confirm current compatibility directly on the extension page.

If your goal is simply to catch broken or wrong links before sending, start with the extension page and test it on one real draft. If you need link safety scanning or click tracking, look elsewhere, since the published description does not claim those features.
