Strict mode has always been broken for me. Firefox replaces some of Google's tracking scripts with no-ops but that usually breaks Google's reCAPTCHA on my end.

Strict mode has always been broken for me. Firefox replaces some of Google's tracking scripts with no-ops but that usually breaks Google's reCAPTCHA on my end. I have to disable tracking protection to make reCAPTCHA sites work. I think it's fair for Google not to fix Firefox's shims, so I don't know who to blame for this. I doubt it's part of some big conspiracy against Firefox, though. I don't think Google cares enough about Firefox to bother annoying Firefox users. Archive.is has had downtime this weekend when I tried to use it. They also regularly pull shady stuff, so I wouldn't be surprised if they did something stupid again and got themselves banned from reCAPTCHA.
