* Use Facebook * Type a status update that's more than one line Expected: box will grow to expand the text if it's > one line Actual: shows only one line, needs some really tricky scrolling to edit the text

w.style.height = Math.max(0 + y.metrics.measure().height, y.originalHeight) + 'px'; y.metrics.measure() inserts the status update text in a PRE tag and measures its height. This way: k.prototype.measure = function() { 'use strict'; var l = this._node, m = this._shadow, n = this._offset, o = i.IS_APPLE_WEBKIT_IOS ? j : 0; m.style.width = l.offsetWidth - n.width - o + 'px'; m.innerText = l.value + '\n'; return { width: m.clientWidth + n.width, height: m.clientHeight + n.height }; }; The problem is that it uses element.innerText to "update" the PRE element. Firefox doesn't support the IEism innerText (yet) so it fails. Using textContent property instead makes it work fine. Harald, can you take this further?

Confirmed bug. In both Firefox & Chrome, the user begins with a single line for status update input. IN Chrome, the box expands downward for each subsequent line of text entered. In Firefox, the box does not expand and only the currently-active line of text is visible. @Harald, can you please provide your thoughts on this?

The question wasn't for me, but these are my thoughts :) IMO Mozilla should implement innerText per bug 264412. However, a workaround on Facebook's side is absolutely trivial and the problem is a real usability issue - it's really not a nice experience to enter long comments on Facebook at the moment. Hence we should reach out and recommend a small fix on their side. It will make their JS more standards-compliant :)

The innerText fix in Nightly solves this problem :-D I'll close this as outreach is no longer necessary.
