webdriver/firebug/netexport works on local but not on ubuntu

[Victor Chan]

Hi,

I am writing a piece of code to capture the traffic of a specific link.

I followed the link http://www.softwareishard.com/blog/firebug/automate-page-load-performance-testing-with-firebug-and-selenium/

and it works perfectly on my local mac.

Here is my preference code:

val profile = new FirefoxProfile()

profile.addExtension(firebugFile)
val FBDomain = "extensions.firebug."
profile.setPreference(s"${FBDomain}currentVersion", "2.0.3")
profile.setPreference(s"${FBDomain}allPagesActivation", "on")
profile.setPreference(s"${FBDomain}defaultPanelName", "net")
profile.setPreference(s"${FBDomain}net.enableSites", true)

profile.addExtension(netExportFile)
val NEDomin = "netexport."

profile.setPreference(s"${FBDomain}${NEDomin}defaultLogDir", logDir.getCanonicalPath)
profile.setPreference(s"${FBDomain}${NEDomin}alwaysEnableAutoExport", true)
profile.setPreference(s"${FBDomain}${NEDomin}showPreview", false)
profile.setPreference(s"${FBDomain}${NEDomin}autoExportToFile", true)
profile.setPreference(s"${FBDomain}${NEDomin}saveFiles", true)

//firefox preference
profile.setPreference("app.update.enable", false)

System.setProperty("webdriver.firefox.logfile", s"${firefoxLogDir.getCanonicalPath}/FFError.log")
System.setProperty("webdriver.logfile", s"${firefoxLogDir.getCanonicalPath}/FFjsConsole.log")

new FireFoxDriver(profile)

However, when I deploy it to my QA box which is ubuntu 12.04.3 LTS, HAR stopped being produced.

Here's my specific:

Selenium-java 2.42.2

Firefox 29 ( was Firefox 31 on my laptop)

Firebug 2.0.3

netExport 0.9b6

I use xvfb-run to allow headless browser to run

The only Firefox error to capture after I supplied the webdriver.firefox.log:

==========================================

Xlib:  extension "RANDR" missing on display ":98".

Can any shed some light out?

many thanks!
