Probably you are right. I use tracker and 3rd party cookies blocking in FF and I often spend 30-60 seconds solving captchas. Often Google says that I solved it wrong (although I try to be careful) so I have to solve it 3-4 times, sometimes with those slowly appearing images. Upgraded my skills of recognising bridges, buses and fire hydrants but still struggle with searching storefronts.
