1474200 - Webextensions code windows ignore ui.caretBlinkTime

Status: NEW

(Core :: Widget, defect, P3)

Description

[MarjaE]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:61.0) Gecko/20100101 Firefox/61.0
Build ID: 20180704003137

Steps to reproduce:

I use Firefox's ui.caretBlinkTime to disable the blinding blinking cursor.

I also try to use Stylus, an add-on, to block certain migraine triggers which basic Firefox cannot block on its own.


Actual results:

Entering Stylus's coding window, I am hit with a blinking cursor.


Expected results:

If users switch ui.caretBlinkTime to disable the blinding cursor, nothing in Firefox, including add-ons, should inflict that cursor.

On the My Filters tab, caret blinking is disabled for the search box, but not the filters box.

We don't have anything to do with caret blink time. I don't know why this would affect only extension windows, but it seems pretty clearly a widget bug.
