Status: RESOLVED DUPLICATE of bug 1312688

(Firefox :: Untriaged, defect)

Description

[Ludwi]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20161019084923

Steps to reproduce:

Go to any page containg flash form with input text field eg http://www.flashdesignerzone.com/tutorials/t1043.php and try write national characters
In my case polish language letters obtained eg by pressing ALT + L

If you are using new profile of Firefox, you have to run Firefox at least twice (at first start there aren't this problem)


Actual results:

Nothing happend, no letter is written to input text field

This problem occurs only if property extensions.e10sBlockedByAddons is set to false (it's default value for new firefox profile)


Expected results:

There should be written polish letter, in case of using ALT + L it is ł

If property extensions.e10sBlockedByAddons is changed to true, after restarting Firefox there aren't this problem

It's due to async plugin drawing.
