Forum capcha problem on Firefox

I just posted over in the General Forum, but it was more hassle than I was expecting.

Logged in to the forum on my Firefox instance (38.0.5 on Windows 7) it wouldn't accept my captcha's. Whatever I did, it just rejected the 'security code'.

I eventually tried logging in using Chrome (43.0.2357.130), and successfully submitted my post, but it made me wonder if anyone else was seeing a problem with the captcha's under Frefox.

Take care,

Mark..........

Thanks David. I appreciate these things are sometimes necessary. Hopefully the problem was just a transient one, since there are no 'me too' replies here.
