I use a Chrome just for watching Twitch streams. Despite Twitch only officially supporting 1080p60fps as the max, streamers are able to feed 1080p90fps or 1080p120fps streams to Twitch's RTMP servers. With my 60Hz monitor, Firefox is an absolute judder-fest when playing these streams, both on my desktop (Windows + Nvidia 2080TI w/HW H.264 decode) and my laptop (Fedora + Intel 630 w/VAAPI HW H.264 decode). Chromium-based browsers seem to handle these streams very well with no noticeable judder.

EDIT: I used to use Webex with Chrome also, but it mostly works fine now on Firefox, even for screen sharing. The only bug I've encountered is that the mute button occasionally doesn't work (audio not muted, but button says "unmute" and has no effect) and I have to rejoin the meeting. When the button works, it stays working for the duration of the meeting.
