Tabs not restored after second crash
Build: Nightly 55.0a1 (2017-05-05); Device: Asus ZenPad 8.0 Z380KL (Android 6.0.1); Steps to reproduce: 1. Go to Settings>Advanced>Restore tabs and set "Don't restore tabs". 2. Open a few tabs. 3. Install the Crash me addon and launch it (or trigger any other crash) twice. Expected result: The tabs are restored when there's a crash, even with "Don't restore tabs" on. Actual result: After the first crash, the tabs are restored. On second crash, the tabs are not restored. The Recently closed tab is opened, but not all tabs that were closed are shown every time.

That's expected in order to break out of possible startup crash loops caused by the currently selected tab. There's one possible improvement for the current code, though: At the moment, the crash counter is reset only if we manage a background-foreground cycle without crashing. What we probably should (additionally/instead?) do is reset it a minute or two after startup if we didn't crash by then. If we absolutely wanted, we could also tweak the number of successive crashes allowed before we disable automatic session restoring. > The Recently closed tab is opened, but not all tabs that were closed are > shown every time. That would require some logs (with "browser.sessionstore.debug_logging" enabled) to further diagnose.
Attached is the log file, from Nightly 55 5/5/2017, where I could reproduce the second issue after a few tries.

How many tabs did you have open before the crash and how many were missing afterwards? Also, were those missing tabs by any chance the most recently opened ones? In the log I don't see anything odd - tabs are written to disk at most every 10 s, so it's expected that the last few seconds of browsing (in this case opening a second tab) can get lost after a crash.
You're right, it takes about 10s for the tabs to be saved and restored after a crash. Wasn't aware of that, thank you. I'll mark this bug as invalid then.
