If you are seeing an extension return after removing it with Anti-Malware for Mac, it may be because of sync settings in Chrome or Firefox. 


Chrome and Firefox both include features that sync extensions between multiple devices. If you are using the syncing features of Chrome or Firefox, it is a good idea to turn off syncing of extensions (or add-ons, as Firefox calls them). This is true in general, but especially so if you are seeing an extension that Anti-Malware Mac removed from one of those browsers suddenly reappear.



  1. Click the Chrome Menu
  2. Click Preferences
  3. Click Advanced Sync Settings under Sign In (If you do not see this, you are not syncing extensions)
  4. Change the drop down from Sync everything to Choose what to sync
  5. Uncheck the Extensions box



  1. Click the Firefox Menu
  2. Click Preferences
  3. Click the Sync category
  4. Uncheck the Add-ons box (If you see options to create an account, you are not currently syncing add-ons)
