We have upgraded the Firefox browser in RBM. If you have configured a website in RBM and using Google Analytics to track actual user visits for the same website, you need to make sure you only use the minor version [dot]247 in Google Analytics to exclude traffic generated from RBM. Not doing so will only have impact on your Google Analytics reporting and will not affect your actual monitoring via RBM.

In RBM, the version of the Firefox browser that plays back the recorded transaction has a unique minor version [dot]247. In the Google Analytics console, you need to exclude this minor-version [dot]247 while tracking website visits.
