1546103 - Delay before text entry on Facebook and Twitter

Status: RESOLVED FIXED

(Core :: DOM: Navigation, defect)

Description

[Andrew McCreight [:mccr8]]

In the last day or so, I've noticed that it takes literally around 10 seconds before I can enter text in a comment on Facebook. The "What's on your mind?" box at the top seems to more or less work, but the "Write a comment..." text entry box that follows somebody's post on the main Facebook feed page takes about 10 seconds before I can type anything into it. Sometimes it seems to take longer.

Text entry on Twitter also seems to be messed up, but the symptom is a little different. I can interact with the text box, but the preexisting prompt text in the box doesn't go away. I don't know if it is the same issue or not.

The symptoms sound similar to bug 1539366, but I only noticed this in the last day or two.

I took this profile, but I can't see anything interesting after what looks like the initial page load:

I used mozregression on my Twitter STR, and ended up with this regression range, containing one bug: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=b97df75c9365a162675d962354083af7b5fb40b9&tochange=98adabf295d0bdd1d48cf715fb8ac8ea4ead8766

Looks like there are some other bugs marked as regressions, so maybe it is a dupe.

Flipping the pref fission.rebuild_frameloaders_on_remoteness_change back to false fixes the issue on both Facebook and Twitter in my regular profile.

The Twitter STR I used for mozregression was something like:

• Go to Twitter. Log in. Dismiss the save your login prompt.
• Click on the "reply" icon on one of the Tweets.
• Click on the text entry box, try to type something.

Ok, I managed to repro the twitter issue on nightly with my main profile. With nightly on a clean profile, I can't seem to get it to happen no matter what I try, which seems odd.

The Google caret issue (Bug 1546019) seems to be happening 100% of the time.

I'm gonna guess there's something with focus and caret/editor that's a problem across all of these bugs, but not duping them against each other quite yet.

Kyle, I believe this is fixed now, right? Should this be closed?
