Steps to reproduce: 1. Launch Firefox for metro. 2. Open at least 3 different tabs. 3. Bring up the tab navigation bar and click on each tile, subsequently. Expected result: Each tab is selected, as the user clicks it. Actual result: After clicking each tab a few times, some of them are no longer selectable for a brief moment. This issue is reproducible on Windows 8 Pro 32-bit using: - the latest Beta (Build ID: 20140303165517)  - the latest Aurora (Build ID: 20140304004003)  - the latest Nightly (Build ID: 20140303030201)   Mozilla/5.0 (Windows NT 6.2; rv:28.0) Gecko/20100101 Firefox/28.0  Mozilla/5.0 (Windows NT 6.2; rv:29.0) Gecko/20100101 Firefox/29.0  Mozilla/5.0 (Windows NT 6.2; rv:30.0) Gecko/20100101 Firefox/30.0
This seems to be only happening when you're using a mouse. Sometimes the click won't get registered and you'll have to click on the tile one more time. This also seems to happen only when you're rapidly clicking through the tabs. - 3 tabs opened, clicking on each one in order and waiting about one second (couldn't reproduce the issue) - 3 tabs opened, clicking on each one in rapid succession (reproduced the issue)
In terms of shipping Metro I do not think this should block shipping in Firefox 28 as this seems to be an edge-case. Please speak up if you disagree.
