A mouse click sequence resulting in a word or line of text being hilighted often fails for me, not because anything is malfunctioning, but because I'm not perfectly still with the mouse while I'm clicking. I want the entire line (or word) to end up being hilighted, but what often happens is that only a portion of the line ends up being hilighted. Here's an example put under a microscope: 1. The user decides to select an entire line of text in a text input of a form. 2. User hangs mouse cursor over text and begins a sequence of three clicks. 3. User completes first two clicks. 4. The user presses down on the mouse button, beginning the third and final click. The line of text is now shown hilighted, but the state of the mouse is still depressed. 5. User inadvertantly moves the mouse a bit before releasing the mouse button, thus causing the portion of text between the mouse and the end of the line to be no longer hilighted. The behavior of the URL bar text is sort of the same, but different. Hopefully there's a fix applicable to both. Here's two possible approaches to a fix: 1. A tiny delay could be introduced, beginning at the 'mousedown' of any click that results in text being hilighted. During this delay mouse movements are ignored with regard to text selection, giving user a chance to release the mouse button without worrying so much about keeping still. 2. Starting at the 'mousedown' of a click resulting in text being hilighted, mouse movements could be ignored in regard to text selection until the mouse travels a certain distance, hopefully filtering out unintended movements of the mouse. Anyway, this is one of those microscopic UI improvements that is so tedious to think about but make the UI that much more "cushy". It's been a minor annoyance for a while, so I'm submitting as 'enhancement'.

Mozilla doesn't behave differently than any other Windows program. Suggesting WONTFIX.
