I have WebDriver 2.41 and Firefox 28 and when my test creates instance of FirefoxDriver I see the following strings in console:
*** LOG addons.manager: Application has been upgraded
*** LOG addons.xpi: startup
*** LOG addons.xpi: Skipping unavailable install location app-system-local
*** LOG addons.xpi: Skipping unavailable install location app-system-share
*** LOG addons.xpi: checkForChanges
.................
How I can turn off this logging?
