1136983 - Crash/Freeze in Nightly when opening Bugzilla page - WER reports Plugin Container for Nightly not responding

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[Karl Mernagh]

User Agent: Mozilla/5.0 (Windows NT 10.0; rv:39.0) Gecko/20100101 Firefox/39.0
Build ID: 20150225030226

Steps to reproduce:

I opened the following page in Nightly 39.0a1 on Windows 10 32 bit

https://bugzilla.mozilla.org/buglist.cgi?j_top=OR&f1=target_milestone&o3=equals&v3=Firefox%2036&o1=equals&resolution=FIXED&o2=anyexact&query_format=advanced&f3=target_milestone&f2=cf_status_firefox36&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED&v1=mozilla36&v2=fixed%2Cverified&limit=0


Actual results:

The page froze just as it started to display the buglist. The progress circle on this tab freezes and all other tabs become unresponsive. I cannot close Nightly and I have to shut it down in Task Manager. This happens with e10s enabled or disabled every time.

Windows error reporting pops up saying that "Plugin Container for Nightly not responding".

If I restore the session, all other tabs continue to work until I click on the tab with the address above. At this point Nightly freezes up. Memory seems to jump to almost 480 mb and CPU to about 15% for the nightly process.


Expected results:

Page should load with no issues

OK, When I actually login to bugzilla and visit the link, I can get the page to load. Memory spikes to 480 mb and CPU for process is 20%. Few freezes occur bug eventually page loads. I've been having issues with LastPass for a while now since Nightly 38. IT causes some Login button to stop working altogether and I have to log out of Lastpass to click on the login buttons. 

Just a stab in the dark but maybe Lastpass was causing this and when I logged in to Bugzilla, Lastpass stopped try to autologin. Could be completely wrong here.

I couldn't reproduce with a clean profile using Nightly 39.0a1 under Win 10 64-bit - the query results were displayed.

I suspect LastPass addon. Websites have been unresponsive at times since Nightly 38. Thanks for having a look.

Karl, did you confirm this, and the problem is gone without the addon?

Hi Wayne,
I enabled the beta version of LastPass and it stopped roughly 90% of my problems. The LastPass addon is blacklisted now in nightly (I assume as I cannot enable without force) but I ran into the same issue again yesterday without LastPass enabled. I believe it is related to this bug

Karl, 

Your other bug has since been closed. Does that mean this problem is gone as well?

No reply from the OP, so I'm marking this as INCOMPLETE.
