Everytime I close a tab (few seconds thereafter) Firefox 3.6.24 writes the following line to console system log (OS X):

.org.mozilla.firefox[7254] Tab close- tab

Curious. Why?

OS X 10.5 Firefox 3.6.24

This is caused by the Firefox addon "DownloadHelper" version 4.9.8.

On line 819 of dhCore.js, it has this statement:

dump("Tab close- "+event.target.tagName+"\n");

In case you're curious, any Javascript can print messages to console.log by using the dump() function, and any addon can hook into browser-wide events like tabs being closed.

You can safely comment this out by prefixing the line with "//" (without the quotes) and restart Firefox. I also raised a bug with the addon developer: http://bugzilla.downloadhelper.net/show_bug.cgi?id=405

You can also try to set the Boolean pref browser.dom.window.dump.enabled to false on the about:config page.

Cor-el,

Thanks for your reply. The pref you mention doesn't exist in my about:config. No prefs containing "browser.dom" or "dump". My FF is 3.6.25.
