The NY Times home page has taken to​ animating many of their illustrations. I would like to prevent that; they​ sometimes cause Firefox on my Windows 11 system to freeze for​ periods of varying length, and I simply don't want them. Their helpbot suggested restarting FF and clearing the cache, both​ proved useless. Changing the setting in Firefox to block audio & video has no​ apparent effect. Videos still play from the NYT page and the browser​ still freezes. Is there a way?
