Several sites that I use require the use of "Captchas", coded words that prove you are a human and not a computer answering a question. I am unable to take advantage of these sites, or offers, because it seems that Firefox does not allow the use of Captcha's, or at least I have not found out how to enable it yet. A good example is that the SF Giants use Captcha's in special circumstances and when that happens, I am unable to participate in whatever is offered and lose out. I am hopeful that someone out there can help me solve this issue. Thank you.
