1269442 - e10s - Firefox Development Edition hangs when opening a website

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[Thomas Radlmayer]

What did you do?
================
1. Startup Firefox and wait until it's finished
2. Open a new tab
3. Enter any website you want to visit and don't have open already, clicking a link in a website also works
4. FF hangs, you cannot switch tabs or anything, CPU-Load to 25%, around 15 seconds later the website appears

What happened?
==============
See Point 4 - FF hangs, it doesnt respond 

What should have happened?
==========================
FF just loads the website normally

Is there anything else we should know?
======================================
Since version 48.0a2 - See https://bugzilla.mozilla.org/show_bug.cgi?id=1269173 - in my case the OS is Win8.1 - Problem happens only in Multi-Threading. I also uploaded a profile from the built-in profiler that shows what happens when site is openened: https://people.mozilla.org/~bgirard/cleopatra/#report=67f9e04a8a3cf4a04bc5dc3fb16c50ae1ef33b5d

Hello Justin, with a clean profile and thus no add-ons it does not reproduce. I guess it will be one of my add-ons/plug-ins acting up.

Comment 5

[Ciprian Muresan [:cmuresan], Formerly of Ecosystem QA - please needinfo @mcoman for things regarding the team]

You could try to disable all add-ons and re-enable them one by one to see which add-on/plug-in is causing this.
However considering that this is related to your custom profile settings, I will mark this as RESOLVED-WFM.
