How to fill tinymce-rails editor with capybara and selenium?

Question

I have trouble with using capybara to test tinymce form. I'm using tinymce-rails and have 7 editors in my form. Also I'm using asciimath plugin with tinymce.

Everything works fine, but I'm unable to write tests to fill in tinymce editor.

Here is how my step definition code looks like, very similar to what is described here:

within_frame("content_ifr") do
  editor = page.find_by_id('tinymce')
  editor.native.send_keys 'test'
end

The problem is when I run the following:

editor.native.clear            # works, clear the editor area, I'm testing this with pry
editor.native.send_keys :tab   # works, moves focus to next input
editor.native.send_keys 'test' # returns "", nothing happens, nothing in editor

So clear and send_keys :tab work as expected. But I can't send any string. send_keys function is always returning empty string, and nothing happens when I do test using pry.

What is going wrong here? and how can I debug / investigate the problem?

Thanks.

Switching to chrome as described here solved my problem.

Obviously the problem is related with a bug in firefox driver.

Still i think it is a valid question for firefox.
