Details

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20160920074044

Steps to reproduce:

Opened https://wiki.horde.org/CalDAV which causes the whole browser to freeze until the non-responsive Javascript dialog `Skript: https://wiki.horde.org/horde/static/d44ba53c7784cf71.js:2` appears.


Actual results:

The browser GUI was blocked for minutes.


Expected results:

There's no need to block more than one tab/GUI component which uses the script. Please use [threads](https://en.wikipedia.org/wiki/Thread_(computing)) for asynchronous computation tasks in order to avoid unnecessary blocks of the GUI.
The issue that blocking GUI should be solved by e10s.
