Firefox Problems?

Since yesterday afternoon it seems like I can no longer post threads or replies to threads in Firefox. I am posting/sending this via Microsoft Edge .

I can seemingly start a thread and can type in the subject field but when I move the curser to the main response box then it wont click in it. Same with PM's too.

It just seems to be with this site as it's not happened on our websites I've been on so far.

Any else having this problem?
