This browser extension can be installed from the Firefox Add-ons site. For known issues, see the issue tracker.
Link Status Redux is a Firefox extension that shows an indicator on the status bar or status popup panel in front of the link address when the mouse cursor is over a link to a page you have bookmarked or visited before. It can also show the date you last visited the linked page.
The indicator prefixes for visited and bookmarked links are arbitrary,
user-configurable text strings. The defaults are a white star (✩,
U+2729) for visited links and a place of interest sign (⌘,
U+2318) for bookmarked links. Remember a trailing space if you want
the indicator separated from the address.
For the displayed visit date, you can choose to prefer visit times that are older than a configurable limit (specified in seconds). This way you can still see the previous visit time even if you happened to accidentally click a visited link. If the limit is non-zero and the link is visited, the latest visit time older than the limit is shown instead. If such a visit time was not found, the very latest time is shown. You can also choose to display both the very latest and the over-the-limit visit times. In this case the latest visit time is always shown and the older visit time is also shown if it a) exists and b) is not equal to the latest visit time.

Custom formatting allows expert users to more freely specify the text that is shown when hovering the mouse over a link (the "link target text"). The specification is done with printf-style substitutions, and the following are valid for the link target text (prefix/URL/postfix in version 3.0):
| Code | Substitution |
|---|---|
| %u | The link URL |
| %T | Custom-formatted link latest visit time, see below; empty string if not visited |
| %t | Custom-formatted older visit time, if it exists; empty string if it does not exist |
| %V | The user-defined visited indicator |
| %B | The user-defined bookmarked indicator |
| %% | A literal % character |
In addition, the following conditional blocks can be used:
| Code | Effect |
|---|---|
| %+( .. %+) | Anything between is displayed only when the link is visited |
| %-( .. %-) | Anything between is displayed only when the link is not visited |
| %+[ .. %+] | Anything between is displayed only when the link is bookmarked |
| %-[ .. %-] | Anything between is displayed only when the link is not bookmarked |
| %+{ .. %+} | Anything between is displayed only when the older visit time %t is defined |
| %-{ .. %-} | Anything between is displayed only when the older visit time %t is not defined |
For the visit time(s), several formats can be defined, which are used when the visit time is more recent than the corresponding time limit. The following substitutions (a subset of those specified by strftime plus the "ago" ones) are valid for visit time formatting:
| Code | Substitution |
|---|---|
| %c | Date and time in locale's preferred format |
| %x | Date in locale's preferred format |
| %X | Time in locale's preferred format |
| %Y | 4-digit year |
| %y | 2-digit year 00..99 |
| %m | Zero-padded month 01..12 |
| %b | Month name from user-defined list |
| %a | Weekday name from user-defined list |
| %d | Zero-padded day of month 01..31 |
| %e | Day of month 1..31 |
| %H | Zero-padded hour 00..23 |
| %k | Hour 0..23 |
| %I | Zero-padded hour 01..12 |
| %l | Hour 1..12 |
| %p | AM/PM |
| %P | am/pm |
| %z | Timezone offset in the form -HHMM or +HHMM |
| %M | Zero-padded minute 00..59 |
| %S | Zero-padded second 00..60 |
| %Ns | # seconds ago with N decimals |
| %Nm | # minutes ago with N decimals |
| %Nh | # hours ago with N decimals |
| %Nd | # days ago with N decimals |
| %Nw | # weeks ago with N decimals |
| %NM | # months ago with N decimals |
| %Ny | # years ago with N decimals |
| %% | A literal % character |
The following is only applicable to the WebExtension version (version 3.0 and later) of the extension.
In addition to the features in the legacy version, version 3.0 adds appearance customization options. You can:
- Choose where the overlink popup is shown: bottom-left corner (see caveat below), above the browser's native popup, or offset from the mouse pointer (warning: may make page mouseover popups difficult/impossible to see).
- Choose to how many lines a very long link URL is wrapped.
- Choose the colors of the overlink popup.
- Write your own CSS rules to style the overlink popup.
The WebExtension API does not allow creating proper UI elements or changing existing ones. This means that the browser's native overlink popup cannot be modified or hidden by the extension. For this reason, the default mode of 3.0 is to show an additional popup above the browser's native one, that shows only the visited/bookmarked indicators and visit time(s). You can configure the extension popup to show "normally" at the bottom-left corner, but you will then have to hide the browser's native popup by editing your userChrome.css. In addition to this, there are other issues which make the WebExtension version not as good functionally as the legacy version. This is why version 3.0 is marked as requiring Firefox 57 or later on AMO: for Firefox 57 users it is better than nothing, but in the author's opinion the legacy version is the better one for earlier Firefox versions. (You can still force-install 3.0 on an earlier Firefox if you want.)
The following is only applicable to the legacy version (version 2.x) of the extension, and is mainly included here for completeness.
In Firefox 3.5 or later, you can choose to stop Firefox from rendering visited links differently. To do so, turn on the "Disable visited link styling" option in the extension preferences. This can prevent a web server from abusing this feature of Firefox to probe which pages you have visited (See bug report). This issue appears to have been fixed in Firefox 4.0 and later and in Seamonkey 2.1 and later.
This extension is a successor to the Link Status extension by fcp, and is based on its code. The main difference is the use of a text prefix instead of an image as the indicator, and that Link Status Redux also works with Firefox version 4 and later. It also works with the Status-4-Evar extension.
