Link Status is a Firefox extension which shows a star icon on the status bar when the mouse cursor is over a link to a bookmarked or visited page. It shows a yellow star if the page is bookmarked, and a white star if the page is visited but not bookmarked. It also shows the date you visited the page last time.
Link Status works not only for text links but also for image links, which usually lack a visual clue about whether they are linked to visited pages or not.
When using Link Status in Firefox 3.5 or later, you can choose to stop Firefox from rendering visited links differently. To do so, select the “Disable visited link styling” (“Ignore :visited link style” in Link Status 1.1 or older) checkbox from the Options/Preferences button in the Add-ons dialog box. By doing so, you can prevent a web server from abusing this feature of Firefox to probe which pages you have visited (https://bugzilla.mozilla.org/show_bug.cgi?id=147777), thus reducing the risk to privacy.
Link Status runs in the following languages: German (de-DE), English (en-US), Spanish (es-ES), French (fr), Italian (it), Japanese (ja), Dutch (nl-NL), Portuguese (pt-BR), Russian (ru-RU). The English version will be used in Firefox in other languages. Thanks to translators!
The icons may not be consistent with your theme.
