After tests are run, I want to collect all console error messages displayed in the console(Open Firebug -> Click on Console -> Click on Errors) using Selenium WebDriver + Java.

Use JSErrorCollector, to collect javascript errors (those coming up in the console) from firefox through java.

it gets as simple as this,

final List<JavaScriptError> jsErrors = JavaScriptError.readErrors(driver);
