1309817 - [e10s] Selectbox stops working after a random time of usage

Status: RESOLVED WORKSFORME

(Core :: Layout: Form Controls, defect)

Description

[Karsten Vorwerk]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20161010144024

Steps to reproduce:

Many customers/user and also our own users, whos firefox is working with e10s report a crash of all selectboxes after some time. Sometimes after 10 minutes after starting firefox, sometimes after 2 hours. There is no special way to reproduce. 
But it won't happen if we manually disable e10s.



Actual results:

If that happend, even simple html-examples for selectboxes won't work anymore.
If i click on it it won't show up the options. All i can do is switch the options with the arrow buttons.


Expected results:

If i click on a selectbox it should show all options in a pulldown field and makes them selectable

Just an additional information.
If it happend once, that behaviour escalates into every tab and every website. All selectboxes won't work anymore.

Karsten, do you still see this problem in recent versions?

Actually we didn't get further reports about it so i can't really say. It might be because we published how to deactivate the e10s function on our server status site.
I also tried to reproduce it but couldn't get it to crash anymore. So might another bugfix fixed this as well.
Thank you.

Let's close it as WORKSFORME, just reopen the bug if the issue is back or reproducible again.
