Uninstalling it will undo most of the changes to your browser(But not the containers themselves yet). The settings that it changes can be found by going to the URL `about:config` and searching for `media.peerconnection` and `privacy.resistFingerprinting`. Make sure that `media.peerconnection.enabled=true` and that `privacy.resistFingerprinting=false`, those are the most important. about:config indicates that non-default settings are in use by putting them in bold type-face. Searching may reveal related settings that were also flipped by the extension. Return them to their default state by clicking the "reset" icon, which is the left-pointing curved arrow on the right-hand side of the page.
