ruby on rails - Capybara 2.1 and Heroku config issue -

-

trying git push heroku part of rails tutorial they're using capybara 2.1 appear causing issue during push. following message:

important! of defaults have changed in `capybara 2.1`. if you're experiencing failures, please revert old behavior setting:  capybara.configure |config|   config.match = :one   config.exact_options = true   config.ignore_hidden_elements = true   config.visible_text_only = true end

the documentation merely says "set these options" followed code above. i'm novice, have no idea set options. best guess in 1 of many files in config, not sure one.

looking @ doc (not version of calybara for) states put configuration file in lib/capybara.rb rather initializer.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
