1195023 - [e10s] IE Tab V2 (Enhanced IE Tab) add-on displays a blank page with a message "plug-in is disabled." in e10s mode

Status: RESOLVED INCOMPLETE

(Firefox :: Extension Compatibility, defect)

Description

[Loic]

+++ This bug was initially created as a clone of Bug #1194942 +++

User Agent: Mozilla/5.0 (Windows NT 6.3; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20150814004009

Steps to reproduce:

The both above extensions are installed and configured.
1. Select a word and then press the right mouse button to select which dictionary to use.
2. Try to switch to the IE rendering engine by clicking the icon.


Actual results:

1. no dictionary select options in the right-click menu
2. a blank page with a message "plug-in is disabled."


Expected results:

Expect to:
1. See dictionary options in the right-click menu
2. Switch rendering engine to IE

Additional info: DictionarySearch functionality is back when I open the page in non-e10s window, but IE engine won't work even in this window (until I uncheck the multi-process box in Preferences.)

With Firefox 57 only WebExtensions are permitted and are, by default, e10s compatible.
