reCAPTCHA issues for Firefox (especially mobile)

[Omegus]

Hello,

It seems the hidden reCAPTCHA is going berserk again and blocking a lot of posts (well, mine) made on Firefox for Android. As the reCAPTCHA is always hidden, it is impossible for me to get through this block (before some smart-ass says something - I'm now typing this on my PC).

Please can you look into switching from the hidden reCAPTCHA to a visible one if verification fails so I can click on 5 street lights or whatever in order to continue posting? The hidden reCAPTCHA is great and unobtrusive, but there needs to be a secondary visible option when it starts causing problems like this.

Thank you.
