Some adware, especially Conduit (aka Trovi, aka SearchProtect), will modify the Firefox app and the Firefox user profile. Some of the known modifications are not trivial to reverse. For that reason, we strongly recommend deleting both Firefox and the Firefox user profile if Anti-Malware for Mac alerts you that you have Conduit.

Deleting Firefox is easy and risk-free:

  1. Quit Firefox
  2. Drag the Firefox app from the Applications folder to the Trash
  3. Empty the Trash.
  4. Re-download Firefox and reinstall it, but do not open the new copy of Firefox yet.


Deleting the Firefox user profile is harder, and will involve some data loss. The following procedure will minimize that data loss, allowing you to save your bookmarks. Beyond that, though, you'll have to rebuild your profile, including all settings, from scratch.

First, you need to back up your Firefox bookmarks. (If you don't have any Firefox bookmarks that you care about, you can skip this step, but be aware that all Firefox bookmarks will be lost if you don't back them up!) To do this:

  1. Click the Bookmarks menu, then click Show All Bookmarks
  2. Click the "star" icon in the toolbar of the bookmarks window and click Backup…
  3. Save the backup file somewhere convenient, like your desktop.

Most people only have one Firefox profile. However, if you have more than one, you will need to repeat this process for each profile, since you will be deleting all of them. Next:

  1. Launch Finder
  2. Click Go, then Go to Folder
  3. Paste the following text into the field:  ~/Library/Application Support/Firefox/
  4. Click Go

This should open a window showing the contents of this Firefox folder. Inside that Firefox folder, you should see a folder named "Profiles" and a file named "profiles.ini". Move both of these files to the desktop.

Now open Firefox. It should open as if it were opening for the first time, which is what it effectively is doing. Get things set back up the way you want, and when you're ready to restore your bookmarks, go back to the bookmark window. Click the "star" icon again, but this time choose the Restore item. Select the bookmarks backup file you created earlier.

If anything goes wrong with the process of deleting your profile, go back to the Firefox folder mentioned above and move the new Profiles folder and profiles.ini file to the trash, then move the old copies of those items that you put on the desktop back into the Firefox folder.
