My experience with it has not been as expected. After initial investigation it can be held responsible for changing DNS settings in router/modem to other than what was set by user. After several scans with different AVs and 3 or 4 OS reinstallation the adware was still persistent. Clicking on any link lead to ad sites and if not one can still see the malware DNS in router/modem. After this addon’s removal things are normal.
Can anyone confirm this???
EDIT : Removal of uBlock Origin did not solve the problem so, uBlock Origin is not the culprit.
