Hi Richard. My name is***** you for your question and the opportunity to assist.
You've got a severe malware infection in Firefox. To clean this up click the 3-horizontal-bar icon
in the upper right corner and select Add-ons. From the menu on the left select Extensions.
On the Extensions page, Disable every item.
Click the 3-bar icon again and select the question mark at the bottom of the window
and select Troubleshooting Information. Click Refresh Firefox, twice
and that will clean up your browser.
I can connect remotely and perform these steps for you if you prefer.
When that is complete go to the link below and download the free version of Malwarebytes Anti-malware.
Under Free Trial, click Download at the bottom of the page.
Install the program, run a scan of your computer and remove any infections found:
Hi Richard. Please let me know if you still need help with this.
