Comment 1 Justin Zobel 2020-10-25 06:12:19 UTC 
I've tested a random episode from www.crunchyroll.com and haven't had any crashes. 

Gary, is this issue still occurring for you on current Qt versions?
Comment 2 Gary L. Greene, Jr. 2020-10-29 01:04:05 UTC 
Hi Justin. I've just tested this. It appears to be resolved with the falkon-3.1.0-24.8 build from openSUSE Tumbleweed, running with Qt 5.15.1 and frameworks 5.75.0
Comment 3 Justin Zobel 2020-10-29 01:07:40 UTC 
Thanks for re-testing Gary.
