Nominating for blocking. I am able to reproduce this on the latest Flame nightly. The window manager button seems to be missing in this instance as well.

(In reply to Florin Strugariu [:Bebe] from comment #0) > also after reproducing this the cards view is not accessible This is another issue which is being dealt with in bug 1092543. > 9. tap the tabs button (or the white area where it should have been) > Actual: > 9. The screen is flashing white a few times then we get a white screen I'm able to reproduce this invisible button issue & screen flashing issue on 2.2. These two issues are NOT present in 2.1, but unfortunately (see below), > Expected: > 9. Nothing happens as we should not have any tabs or browsing history This expected behavior is NOT present in 2.1 either. In 2.1 the show window button is visible at step 9 and after tapping on it, browsing history is shown in tabs/windows. I will work on finding the window for the white screen behavior but for the expected behavior I think another bug needs to be filed and it doesn't look like a regression since it happens on 2.1.

Regression window shows that this issue is related to bug 1092543 afterall because they're both broken by the same bug 1073252. Also please be noted that the 'Working' build's behavior here is NOT the expected behavior because it still shows history, as mentioned on comment 2. ------- mozilla inbound regression window: Last Working Environmental Variables: Device: Flame BuildID: 20141031020755 Gaia: 8ae6598f3ab7b0c34ac42a73083ddb74266affba Gecko: 287ddaf9b9df Version: 36.0a1 (2.2 Master) Firmware: V188 User Agent: Mozilla/5.0 (Mobile; rv:36.0) Gecko/36.0 Firefox/36.0 First Broken Environmental Variables: Device: Flame BuildID: 20141031021654 Gaia: 8ae6598f3ab7b0c34ac42a73083ddb74266affba Gecko: 52d9cbc1d78e Version: 36.0a1 (2.2 Master) Firmware: V188 User Agent: Mozilla/5.0 (Mobile; rv:36.0) Gecko/36.0 Firefox/36.0 Gaia is the same so it's a Gecko issue.

possibly broken by Bug 1073252. Can you take a look Robert?

Please retest after 1092543 has been fixed.

Pi Wei, please restest this now that bug 1092543 has been resolved as fixed. Thanks!

Issue is verified fixed on latest 2.2. Observed behavior: At step 9 of original STR the device does NOT display a white screen (browsing history is still displayed though, as mentioned in comment 2).
