User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20150125222008 Steps to reproduce: See http://jsfiddle.net/8ea7aff2/ 1. Click in "I am div number one" to place cursor 2. Click in the "I am not editable" in the first div; entire div is selected 3. Click in "I am div number two" 4. Click in the "I am not editable" in the first div again; cursor appears this time Actual results: In step 4, the cursor appeared in a ce=false area. Expected results: It should not be possible for the cursor to appear in a ce=false area. Firefox prevents this correctly when the cursor is moving within ce=true container that contains the ce=false node like in #2 (it selecting the text isn't correct, but that's bug 1097242), but when the cursor moves from a different ce=true container, this is not prevented. In Chrome, the cursor does not enter the ce=false area when you click in it, regardless of whether the selection came from the same ce=true container or a different one.

Trying a fix: https://treeherder.mozilla.org/#/jobs?repo=try&revision=4d2ef5bb81f6

sorry had to back this out for perma test failures like https://treeherder.mozilla.org/logviewer.html#?job_id=6968411&repo=mozilla-inbound

Second try: https://hg.mozilla.org/integration/mozilla-inbound/rev/99419a04c349 Had to disable selection carets in addition to touch carets.

This was backed out from Fx40/Fx41 for causing bug 1181130.
