This is a very rare scenario. Rapport blocks unauthorized browser add-ons from accessing the browser. Some add-ons are badly designed and do not handle blocked requests properly. As a result the add-on crashes and causes the browser to crash (as the add-on is part of the browser's process).
We are constantly testing Rapport against hundreds of browser add-ons. However, due to the huge number of add-ons you might be running an add-on that was not tested with Rapport and does not properly handles Rapport's blocking activity.
