It is impossible (for me) to log in to this forum using Firefox Browser because the Captcha button that says 'I am not a robot' will never return. I have let it sit for hours spinning its little blue arrow to no avail.
This is coming to you by way of Chrome.
I am writing you this comment from firefox after passing the captcha test. It could have been a faulty moment in WIX infrastructure or maybe a specific firefox version that does this. But not witnessed an issue here.
