LG G8 with Firefox for Android

82.1.1 (Build #2015770923) AC: 60.0.5, a1a471ddc GV: 82.0-20201014125134 AS: 63.0.0

Sometimes if I swipe up/down to scroll a web page Firefox will ignore me until I lift my finger and try again. Occasionally the first retry will fail as well. As far as I can tell, this affects web site taps, pinches, and swipes. I know Firefox is getting some kind of input because the address bar on the bottom will appear even though the website doesn't budge during a swipe. Some taps go completely ignored.

This started about a week ago (presumably when 82.1.1 came out--Wednesday 10/21 @ 5:28 AM). None of the native Firefox interface elements have exhibited this problem. Some of the other elements which seem like they might use the same facilities to render themselves as a web page would do, in fact, show this problem. I cleared data and cache, went to sign in again, and Firefox completely ignored my first tap on the email address field. I had to tap again. I have no problems whatsoever in any other application on my phone. I have no problems with web pages in Chrome for Android or in the system WebView (e.g. links clicked through the Gmail app). I encountered the problem on support.mozolla.org 3-4 times just trying to figure out how to submit a support request post. I subsequently switched to Chrome to post this and have had no issues whatsoever navigating around this or any other site.
