User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170302120751

Steps to reproduce:

Typing on the chat input.


Actual results:

Trying to type on the chat input box is laggy, very uncomfortable.

E10s on and off. Hardware Acceleration on and off.


Expected results:

It should be a smooth experience.

Tested on Maxthon(Webkit engine, not Blink) and SlimJet(Chromium variant) chatting in the field is smooth and responsive.

Note: Weak laptop (A6-6310 SoC, 4GB RAM with 8G ReadyBoost, HDD).
Note 2: Tested on my desktop and its unbearable with e10s disabled, try typing over time and it we have to wait for the letters to finish displaying before continued typing, note that "over time," not when you begin.
Desktop is FX-6300 with 8GB RAM, Samsung 850 EVO SSD.
Both with Windows 10 Home 64-bit. Laptop Firefox 52 BETA RC2 32-bit FX and desktop Firefox 51.0.1 64-bit.

Kudos on Twitch being bearable without e10s on my laptop, seriously a great job. Really smooth with e10s. Testing Palemoon and typing is a bit stuttery at times, so I take it the Twitch portion was fixed on the Firefox's core.

Don't get me started with e10s disabled on Yahoo! Mail, even my desktop feels that when scrolling through the e-mails but with e10s it is smooth as butter on my laptop and desktop.

Any url or chat demo to test?

Any streamer page, so just pick one randomly.
But I guess I can use this popular one: https://beam.pro/Monstercat


I also noticed less jank on my desktop. Must be that the developers got working on it, when I reported this 3 weeks ago. Yet, I understand that Maxthon and SlimJet have different engines so it is not an apples-to-apples comparison when indicating "how they perform so well."
I know I might get a reply with "I am not experiencing any problems with the keystrokes," yet the user might be using a more powerful computer, needs to be similar to mine.

For test sake, try to spam your keystrokes and when you have many, press-and-hold the Backspace key, until you clean the input.
I type fast so I catch up to the uncomfortable portion. Happens even when I see the stream player play or not.

Well, a friend was streaming on HitBox.Tv and all the browsers tanked on my laptop, it's very resource intensive, only gets worse when that site has been this heavy for over a year.

But is the problem fixed? It still happening to me, while 52. 
I think that it is the repainting problem that was happening in YouTube.
Or does anyone know what it is to report it to BEAM?
I have to keep using Chromium or Maxthon because they aren't affected.

[megarig_2000]

Ah, I see what you did there. I thought since 52 is phased-out, the whole thing is won't fix and ignored.

This can be closed, they changed their site scripting or something. It's smooth-ish, almost no stops, must be both Mixer's team and Firefox.
