Instead, the right most tab is displayed. Reproducible: Always Steps to Reproduce: 1. Open Firefox 2. In Options -> Tabs -> uncheck "When I open a link in a new tab, switch to it immediately" 2. Navigate to a website with links 3. open some links in new tabs in background 4. bring the last opened tab opened tab to front by clicking on it 5. close this tab Actual Results: you see the roght most tab Expected Results: see the tab I was before My firefox is set to open new tabs in the background. When enabling "When I open a link in a new tab, switch to it immediately" under Options/Tabs, this bug doesn't appear, i.e. when closing a tab the previosly shown tab is shown again.

I cannot find another bug on this issue. So lets confirm with Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2a2pre) Gecko/20090901 Namoroka/3.6a2pre ID:20090901173911

It's more obviously a dupe of bug 345033.
