The error occurs inside a each loop (after 1 till 2 minutes), regardless if I watch the Firefox or let it run headless.

What could I try?

Answer 1

I've just figured out. In your env.rb you are setting up capybara but you are creating browser using watir. That's not good because capybara and watir at the same time may produce a conflict. Switch Capybara off. Use only watir. Do not put 'capybara' to require. That's much more good suggestion than mine suggestion in a comment. But I am still not 100% sure. Try it please.

Answer 2

This link did the trick: https://watirmelon.com/2013/05/16/stop-firefox-auto-updating-and-breaking-your-ci-build/

With global debug enabled I could see, that a h264 addon inside Firefox was trying to update and breaking the build.

Thanks four your help guys!
