Firefox crashes continuously on iOS 15.6

Hi,

My apps are automatically updating so I cannot tell what triggered these crashes. But Firefox now crashes continuously, as soon as I start the app.

I am running an up to date iOS 15.6 on iPhone XS.

It is impossible to use Firefox on my iPhone, not even for one second.

I hope you can fix this.

Hi

I have been advised by our developers that there is a potential fix for this issue in Firefox for iOS 109, which is due out in just over a weeks time.

If that does not fix it, please come back here, reply to this thread and we can look into it further for you.

Hi,

thank you for your answer but it looks like an automated answer:

  1. 1. Firefox is perfectly up-to-date
  2. 2. I am experiencing the crash on a iOS 15.6 iPhone, not on a Windows computer.

I am no longer able to run Firefox Browser on my iPad or iPhone since the late Nov update. Please fix this! It crashes immediately on both devices.

Hi, following on recent updates, it works a bit better but as soon as I log into my Firefox account and try to sync it, it crashes.

Hi

I am sorry to hear that Firefox for iOS is crashing. I hope that we can help resolve this for you. Before following the steps below, please make sure that you have updated both your iOS device and Firefox for iOS to the latest versions available.

As a first step, close down many of the tabs that you have open to as few as possible. Does this help reduce the incidence of a crash?

If this does not help, open the iOS Settings app, select General then iPhone Storage. Find Firefox and select Offload App. Does this help?

Failing that, we will need to look into this in more detail with some logs from inside your copy of Firefox for iOS:

  1. Launch Firefox.
  2. Open Settings.
  3. Scroll down to Version and tap it several times.
  4. Scroll down and hit "Debug: copy log files to app container". This triggers the logs to be saved into the Documents folder.
  5. Open the Files App on your iOS device and navigate to Fennec > Logs. You can see the different logs files here, which you can export using the share menu from Apple to a desktop computer.
  6. Copy and past the full report into https://paste.mozilla.org/, setting the two options at the top to Plain Text and Expire in one week.
  7. Select Paste Snippet on the right hand side, then copy and past the link into a reply to this thread.

I hope that this helps.

Hi,

I am now running IOS 16.2 and the latest version of Firefox iOS, but it keeps crashing, within seconds after opening it (if not immediately). I reinstalled it many times, to no avail. I am posting the logs you requested on paste.mozilla.com

Thanks a lot for your support, this is really annoying and Safari is a pain.

Best regards,

Philippe
