text-overflow:ellipsis in Firefox 4 (and FF5): A Comprehensive Guide
In the world of web development, the text-overflow:ellipsis CSS property stands as a testament to Microsoft's foresight. This property allows text to overflow an element's boundary and be truncated with an ellipsis (...) indicator.
Unfortunately, Firefox has been lagging behind other browsers in its support for text-overflow:ellipsis. The Firefox developers have debated the issue for years, but implementation remains elusive.
The Demise of the -moz-binding Hack
Once upon a time, Firefox 3 users could resort to a hack using the -moz-binding feature to enable ellipsis support. However, this solution hit a roadblock with the removal of -moz-binding in Firefox 4.
JavaScript as a Last Resort
Developers may consider using JavaScript as a fallback. jQuery offers a simple solution for truncating text:
var limit = 50;
var ellipsis = "...";
if( $('#limitedWidthTextBox').val().length > limit) {
var trimmedText = $('#limitedWidthTextBox').val().substring(0, limit - 4);
trimmedText += ellipsis;
$('#limitedWidthTextBox').val(trimmedText);
}
A More Elegant Approach
For a neater solution, attach a CSS class (e.g., fixWidth) to elements with fixed widths. Then, use JavaScript to handle truncation for all elements with this class:
$(document).ready(function() {
$('.fixWidth').each(function() {
var limit = 50;
var ellipsis = "...";
var text = $(this).val();
if (text.length > limit) {
var trimmedText = text.substring(0, limit - 4);
trimmedText += ellipsis;
$(this).val(trimmedText);
}
});
});
Firefox's Redemption
Finally, after years of anticipation, Firefox Aurora has incorporated ellipsis support, paving the way for its release in Firefox 7. This long-awaited feature brings Firefox up to par with other browsers, offering developers a native solution for ellipsis truncation.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
