490819 - Allow about: protocols to be navigated in content tabs

Status: RESOLVED DUPLICATE of bug 497570

(Thunderbird :: Mail Window Front End, defect)

Description

[Mark Banner (:standard8)]

Attachment: Partial Patch

For bug 480533 we want to open various about: pages in tabs - some of these have links between them (e.g. one to be implemented in bug 490817), and hence we want the user to be able to click on them without opening new tabs.

I've had a little bit of success implementing this - see attached patch.

This patch makes it so that when we click on an anchor link, we'll move to the correct part of the page. However when we click on a link to a different about: page then we try and save the page (or open externally) rather than display it in the same tab.

I thought it could be because the content type is set to "content" rather than "content-primary" or "content-targetable", however it doesn't work if we show it on the message pane (which is currently content-primary).

You can open a content tab by entering the following in the error console:

Components.classes['@mozilla.org/appshell/window-mediator;1'].getService(Components.interfaces.nsIWindowMediator).getMostRecentWindow("mail:3pane").document.getElementById("tabmail").openTab("contentTab", "about:license", "about:license");

I've not got time to work on it, though it'd be really nice to have in TB 3.

I'm doing this work in a more generic manner in bug 497570. Therefore marking as duplicate of that bug.
