767102 - Shutdown hang involving sync XHR

Status: RESOLVED INCOMPLETE

Attachment: hang sample captured by Activity Monitor

I tried to quit Firefox with only my app tabs (Gmail, Reader, Twitter) open.  The window went away but the app kept running.

I think this was with yesterday's nightly. I had an update pending.

I hit this again today.  I tried to shut down Firefox while my uplink was down.

Related to bug 705617?

Benoit, have you collected any shutdown profiles matching Jesse's?

Comment 5

[Benoit Girard (:BenWa)]

No, we wont capture profiles if the shutdown doesn't complete.

It might be worth checking anyway.  It's possible that a slow (rather than unresponsive) server would result in a slow (rather than hangy) shutdown.

Hi reporter,

I am not able to replicate the issue. I've tried on windows 10 pro, firefox 85.0.1 (64-bit)
Is this issue still ocurring to you? If so, can you test the issue while in Safe Mode. You can find helpful info here : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode .

If possible, you can test this issue on the nightly build as well. Download the build from : https://www.mozilla.org/en-US/firefox/nightly/all/ .
Thanks for the report.

Best regards, Clara.

With e10s, we'll kill content processes that are hanging with sync XHR, so this is less of an issue.
