Rails frontend developer toolset

Xilence

There is only one extremely useful feature:

Xilence removes all that annoying HTML and CSS code from your rails backtrace for ajax requests

Just open your firebug/safari console and click on the following link

In Rails 3 and Bundler, add the following to your Gemfile:

group :development do
  gem 'xilence'
end

If you still use rails 2, look at rails_2 branch.
