This occurs regardless of the state of the dom.disable_window_status_change preference. The issue has been observed on numerous websites. All my browser plugins are disabled. Reproducible: Always Steps to Reproduce: 1. Navigate to a site that has javascript that makes use of the window.status property (i.e. http://w3schools.com/js/tryit.asp?filename=tryjs_statusbar or http://www.htmlgoodies.com/beyond/javascript/article.php/3470771 2. Verify on the about:config page that the preference "dom.disable_window_status_change" is set to "false" 3. Move the mouse pointer over the link with the 'onmouseover' event Actual Results: The status bar shows the url referenced by the hyperlink. Expected Results: The status bar should display the text which javascript has set 'window.status' to. No plugins are enabled. Using default theme, after install of Firefox 3. This behavior was not present in versions of Firefox 2.

I'd say this is a duplicate of Bug 343847. If you think it's not, can you provide a testcase or steps to reproduce with URLs etc.

This is a simple HTML file that makes use of the window.status property. Loading the page should update the status bar.

This is a simple html file which demonstrates the issue. The status bar should update when the user mouses over the link.

While possible that this is a manifestation of the same root cause, this is a different manifestation of the issue. I cannot say if the cause is identical. Bug 343847 requires the user to move between tabs to reproduce the issue. This bug occurs regardless of how many tabs are open, and occurs without tab switching. I have attached two simple html files in addition to the links provided in the bug description. Hopefully someone can determine if these two issues are identical. The first file (HTML Example 1) makes use of the window.status property, and works as expected. The second file (HTML Example) - sorry, forgot to rename it- demonstrates the issue. The text in the status bar should change when the link is moused over. Instead, 'www.google.com' appears. After the mouse is moved off the link, the status bar changes to the text set by the javascript. However, many websites change the status bar text again when the onMouseOut event occurs. This renders the onMouseOver status bar change useless, as the user never sees the updated status bar.

Not going to block on this, but we would consider a fix if a safe one is provided.

This works when the status text is set on the onmouseover event, but it isn't fired until the mouse is taken off the link itself. So, if one has an onmouseover an onmouseout event that change the status based on if the mouse cursor is over the link or not, it does not work at all. See attached file.

Sorry forgot the builds. Both of these browser have the same issue: SeaMonkey 2.0.3 Firefox 3.5.7
