When I close my browser, I get the following error message: TypeError: utils.getPref is not a function
Can Anybody tell me what this error means in english?
Other than that, great Add-on.
Please try the latest version 1.48.3

It is not reviewed yet by AMO, but fixes a few bugs of the current version including possible namespace conflicts with other addons (which seems to happen in your case)
