Setting the disabled state (attribute) on a tab does not act as I would expect. Current behaviour: The tab text will dull, and the onfocus event will not be executed. However, it will still switch to the tab and display the tabpanel contents. Expected behaviour: Dulling of text, non-execution of code and not allowing the tabpanel to be displayed. Assigning to hewitt as per hyatt's request.

question: how can one put a tab as disabled? I only see close tab, close other tab, new tab, bookmark this group of tabs, reload tab, reload all tabs. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a4) Gecko/20040927

Thomas: XUL is intended as a toolkit for building applications, and those applications may have other uses for tabs besides just what Mozilla browsers expose ;-) This patch looks pretty reasonable to me, but I'd need to further study other bindings to ensure that this is implementing the disabled property in a consistent manner.

Reassigning to me so that this is at least on my radar.

The patch does nothing to address keyboard navigation between tabs.

I'd say this patch has bit-rotted a bit. Anyone interested in me making another one?

Can confirm this bug is still here FIVE YEARS after first report. Tabs recieve focus whether they are disabled by property or attribute. Maybe the next decade will bring a fix ;-)

Here are the other related bugs I found to the XUL tab. https://bugzilla.mozilla.org/show_bug.cgi?id=366116 https://bugzilla.mozilla.org/show_bug.cgi?id=261826 https://bugzilla.mozilla.org/show_bug.cgi?id=307088 Affected are the hidden, disabled attributes/properties as well as the ordering of tabs.

requesting blocking1.9; this bug is ancient, relatively easy to fix (good first bug), and useful for Gecko app developers and extension developers.
