Overview
TargetAlert is an extension for the Firefox web browser that provides visual cues for the destinations of hyperlinks.If a hyperlink points to a something that is not a web page, then TargetAlert will try to append an icon to the hyperlink that represents its destination. For example, a hyperlink that points to a PDF document would look like this when using TargetAlert:
Sample Link to a PDF
This has two main advantages over plain hyperlinks. First, it makes links to PDF documents easier to find on a web page. Second, if you do not enjoy the "surprise" of clicking on a hyperlink and discovering that it links to a PDF document, you can use TargetAlert as a visual warning. See Features to see what other file types TargetAlert supports.
The current version of TargetAlert is: 0.8.9.8
Author's Note (2005-05-31): TargetAlert 0.8 has been released. Although on the surface it may not appear much different than version 0.7.4, it has been completely rewritten to provide support for a number of requested features, including the support for user-defined alerts. Many of these features have been implemented internally but are not yet exposed through the UI. These features will gradually be introduced over the next few weeks in the 0.8.x version series. For more details, see the Version History.
