Reproducible: Always Steps to Reproduce: 1. Open Firefox integrated with Tab Candy 2. Open another tab. 3. Switch to the First Tab. 4. You return back to the First Tab with it being the only tab left in the Browser.

Disappeared New Tab is found in another Tab Group in the Visual Tab Interface. Is it intended that switching to another tab from a New Tab automatically make that new tab in a new group?

It appears that it works as expected. See the below code in mozilla central http://mxr.mozilla.org/mozilla-central/source/browser/base/content/browser.js#7744 I don't see the disappeared new tab appears in another Tab Group. Might be something you created before?

When I was testing this, I was using an old build. Sorry I forgot to check on this in a latest build. I have checked that this bug still exist but everything in comment 1 cannot be reproduced. Current status of Bug: After switching over to another tab, the New Tab is closed instead of disappearing. In the old build, it "reappears" in the visual tab interface. In the latest build however the new tab is closed as it is not even at the visual tab interface. Is it intended that Blank New Tab are closed after using them to switch to another tab?

As I mentioned in comment 2, this is the default behaviour of Firefox which the selected blank tab would be closed if you use the "switch to tab" feature. Please give the official beta build a try.

I didn't realised that this was the default behaviour. Sorry Marking This bug as invalid.
