It's not that it doesn't work, it's that there is an anecdotal bias towards making you do more work to prove you're not a robot.

I don't use Chrome, so I can't tell how bad it is on a comparative basis, but (especially in private browsing mode) Recaptcha can make you cycle through a half-dozen different images looking for the traffic lights or what not before letting you continue.

That's when I just leave. If I'm feeling nice, I'll drop the site owner a note explaining why, but usually not.

Nobody's site is that great.

I had to stop ordering from Newegg because they wanted me to recaptcha just to log into my account. It seems to be fixed now, though.

Sure it works be Google will make ff do more steps and even load the images slower on the "click till non match" ones
