Remove malware from Firefox for Mac

To remove malware from Firefox for Mac we will reset the browser settings to its default. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history, and open tabs.

Go to the “Help” menu.

Click on Firefox’s main menu button, represented by three horizontal lines. When the drop-down menu appears, select the option labeled “Help“.
Click “Troubleshooting Information”.

Next click on the “Troubleshooting Information” option as indicated by the arrow in the image below. This will bring you to a Troubleshooting page.
Click on “Refresh Firefox”

Click the “Refresh Firefox” button in the upper-right corner of the “Troubleshooting Information” page.
Confirm.

To continue, click on the “Refresh Firefox” button in the new confirmation window that opens.
Click on “Finish”.

Firefox will close itself and will revert to its default settings. When it’s done, a window will list the information that was imported. Click on the “Finish“.

Your old Firefox profile will be placed on your desktop in a folder named “Old Firefox Data“. If the reset didn’t fix your problem you can restore some of the information not saved by copying files to the new profile that was created. If you don’t need this folder any longer, you should delete it as it contains sensitive information.
