261657 - flickering title bar

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Frederik Himpe]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040926 Firefox/0.10
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040926 Firefox/0.10

When visiting http://www.extrasoft.be, the title bar of Firefox (but also
happens with Mozilla 1.7.x) starts flickering. Also the entry in the task bar in
KDE or Windows XP starts flickering. In KDE, you see that all CPU time is being
used by the firefox-bin, kicker and X processes (each using about 33% of CPU
time). The result is that the whole system is becoming very unresponsive and you
are forced to close the browser. If I waited for some time, I even had to kill
the firefox-bin process, which in itself was even very difficult, because it
took a very long time to log in in a console. For that reason, I have put the
severity to Critical.

Reproducible: Always
Steps to Reproduce:
1. visit www.extrasoft.be
2.
3.

Actual Results:  
title bar and taskbar entry start flickering, system becomes very unresponsive
in Linux

Expected Results:  
show the site without excessive CPU usage and without updating the title bar all
the time

The flickering is caused because the one who made that page constantly updates
the tiltlebar

<SCRIPT LANGUAGE='JavaScript'>

var default1 = "Welkom bij WWW.EXTRASOFT.BE"; // wordt 1 keer getoond als pagina
laad
var text1 = "Welkom bij WWW.EXTRASOFT.BE";
var text2 = "Welkom bij WWW.EXTRASOFT.BE";
var text3 = "Welkom bij WWW.EXTRASOFT.BE";
var changeRate = 1; // 1000 = 1 seconde

var messageNumber = 0;

function changeStatus() {
  if (messageNumber == 0) {
     window.status=default1;
     document.title=default1;
    }
  else if (messageNumber == 1) {
     window.status=text1;
     document.title=text1;
    }
  else if (messageNumber == 2) {
     window.status=text2;
     document.title=text2;
     }
  else if (messageNumber == 3) {
     window.status=text3;
     document.title=text3;
     messageNumber = 0;
     }

  messageNumber++;
  setTimeout("changeStatus();",changeRate);

}

changeStatus();

// -->
</SCRIPT>

Complain to the webmaster, nothing FF can do about this
