You are correct. If I open/load FireFox and double-click in the titlebar a new tab is
opening. I was incorrect in stating that it did not open upon loading FF. I must have been closing a tab and can confirm this is the issue that I'm seeing. This is consistent when double clicking to open a new tab after closing a tab via the close button and does not matter if FireFox is maximized, full screen, or windowed.
Thank you for pin-pointing the issue and confirming. Hope there is a possible fix available in the future - for now I can live with it.
On an off-topic, I posted a question/request in the Request forum, and was just wondering if my request was at all possible for a future build or not possible. It's regarding being able to automatically have a tab protected based on it's URL.http://tmp.garyr.net/forum/viewtopic.php?f=4&t=16396
