The script will be a bit overkill, but if you comment out line 171-172 and add <code>this.setIcon(self.icons.read);</code> below, it should set the icon to the red envelope, and not incur anymore overhead. So, to sum up, line 171-172 changes from: <pre>this.timer = setInterval(this.poll, 500); this.poll();</pre> To: <pre>//this.timer = setInterval(this.poll, 500); //this.poll(); this.setIcon(self.icons.read);</pre> I have tested it to work in Firefox 3.5 on Windows XP. <p>The script will be a bit overkill, but if you comment out line 171-172 and add <code>this.setIcon(self.icons.read);</code> below, it should set the icon to the red envelope, and not incur anymore overhead.</p> <p>So, to sum up, line 171-172 changes from: <br /><pre>this.timer = setInterval(this.poll, 500); this.poll();</pre> <br />To: <br /><pre>//this.timer = setInterval(this.poll, 500); //this.poll(); this.setIcon(self.icons.read);</pre></p> <p>I have tested it to work in Firefox 3.5 on Windows XP.</p> 2009-07-14T16:38:40Z 24430 Script 146133 30765 2009-07-14T16:38:58Z Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729) 27555
