User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20161128075558

Steps to reproduce:

On Mac OSX (at least last three versions). I have been unable to reproduce this on windows 7, 8.1 or 10.

In a text form field in a silverlight web app that filters a database list I typed the sentence "its time to test".
Test Case 1
1. Navigate to form field that filters database items. E10s must be enabled.
2. Begin typing in the field.
3. Expected output will not match keyboard characters precisely.
4. This problem recurs with new profiles

Test Case 2
1. Turn off E10s by changing browser.tabs.remote.autostart(x) to false.
2. Navigate to form field that filters database items.
3. Begin typing in the field.
4. Expected output will match keyboard characters precisely.



Actual results:

The field picked up the characters "itteeeeeeeeeeeeeee"


Expected results:

The field should have picked up the characters "its time to test"


Notes : 

1. This is a medical software with subscription access. I may be able to work with someone privately to provide credentials for testing and validation.

2. This is highly reproducible by users with the correct operation system. (10.12X, 10.11X, and 10.10X) 

3. Initial reports began with version 48 of production.
