1330003 - enter or copy paste text into a Flash text field does not work - intermittent

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect, P3)

Description

[reginaldlather]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170105155013

Steps to reproduce:

This is an intermittent fault with no actual user action to initiate the fault


Actual results:

after entering text into a Flash input text field and then trying to repeat the process, occasionally, although the text box allows focus, I cannot enter or cut and paste any text at all. This happens even with dom.ipc.plugins.asyncdrawing.enabled = false. Other browsers and Flash IDE are not affected.


Expected results:

Text should be enterable at any time.

I can reproduce - Scenario: 
Have multiple tabs open, select any tab other than the target tab with the Flash App.
Select 'ALT' and the menu for firefox appears.
Select the target tab. Text field allows focus but data cannot be entered into text field. If there is already text in the field, it cannot be cleared. It is as though all alphanumeric and backspace keyboard activity is lost.
Even if I select another tabs and then go back to the target tab, the issue remains.
Now, whilst on target tab, select 'ALT' again and the menu firefox menu appears.
Select 'ALT' for the third time, the Firefox menu disappears and now the textbox is active once more and able to accept text.
This only affects input text field. Dropdown combos, radio buttons and checkboxes still function as expected

Hope this helps

Alice does this work with non-e10s win64 (plugin sandboxing still on)? This seems like it would be more likely to be a sandboxing issue.

Yes, it works.

Strangely, if the following step is added, the problem does not occur. 

4.5.  Click on location bar do that location bar will get focus.

Getting late for 52.  Benjamin, any idea what might be going on with flash and e10s here?

Comment 8

[Liz Henry (:lizzard) (relman/hg->git project)]

Marking this fix-optional for 53 as there is a workaround (disabling e10s) and we aren't shipping 64-bit by default yet.

Resolving as wont fix, plugin support deprecated in Firefox 85.
