1413354 - Firefox Android Beta 57.0 crashes at every launch

Status: RESOLVED DUPLICATE of bug 1411330

(Firefox for Android Graveyard :: General, defect)

Description

[Claas Augner [:claas]]

Attachment: adb-logcat.log

I have been using Firefox Beta on Android for more than one year. About two weeks ago (~ 15th October 2017), the app began crashing immediately at every launch, i.e. it has become unusable and I had to use Firefox Nightly meanwhile.

However, I would like to be able to use Firefox Beta again, last but not least because I have several passwords saved in the corresponding profile.

Please find attached the full adb-logcat.log for such a crash. It contains all log messages between the start of Firefox Beta and the start of the Firefox CrashReporter.

What I noticed in the logs:

1. ActivityManager: Scheduling restart of crashed service org.mozilla.fennec/org.mozilla.gecko.customtabs.GeckoCustomTabsService in 1000ms
2. GeckoConsole: Could not read chrome manifest 'file:///data/user/0/org.mozilla.firefox_beta/chrome.manifest'.
3a. GeckoCrashHandler: >>> REPORTING UNCAUGHT EXCEPTION FROM THREAD 130386 ("IntentService[GeckoTelemetryUploadSerWorker]").
3b. GeckoCrashHandler: java.lang.IllegalStateException: Expected file to exist but got exception in thread: IntentService[GeckoTelemetryUploadSerWorker]. File info - existence: true, can write: false, size: 739.
3c. GeckoCrashHandler:     at org.mozilla.gecko.telemetry.stores.TelemetryJSONFilePingStore.lockAndReadJSONFromFile(TelemetryJSONFilePingStore.java:242)

Actually bug 1411330 might be a better fit, since for you these crashes started happening only with Firefox 57.

Thanks, Jan. Actually, the logs meanwhile helped me to come up with a workaround (because Telemetry upload requires network):

1. Enable flight mode.
2. Open Firefox Beta.
3. Disable Telemetry and Health Report.
4. Close Firefox Beta.
5. Disable flight mode.
6. Open Firefox Beta again.
7. No crash.

(And this explains why Firefox Beta sometimes actually didn't crash immediately, namely when my phone didn't have a network connection.)
