Make use of Adblock Pro Extension to block

• https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/

You got either adware / malicious plugin or an malicious proxy server set up. Scan with malwarebytes.

Thanks guys! The adblock works! The scanner didn't find anything. Will keep it running. God bless! Mike

AdBlock seems to have stopped working. I restarted my computer, and the pop-ups are back! The Add-on is still listed, however, and is not disabled. Thanks! Mike

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

Can you post a link to a publicly accessible page where you see this that doesn't require authentication (signing on)?

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.

Make sure that you update each program to get the latest version of their databases before doing a scan.

I found the problem on their website:

Adblock Plus icon and Adblock Plus entry in Tools menu don't appear after installation Cause 1: Adblock Plus extension is disabled

When opening the Add-on Manager (menu Tools / Add-ons) and finding Adblock Plus under extensions, the entry is gray rather than black (disabled).

Solution: Click the Adblock Plus entry in Add-on Manager and click the "Enable" button. Cause 2: Mozilla bug 770669

This can happen due to a browser crash after updating from Adblock Plus 2.0.x to a newer Adblock Plus version.

Affected: Adblock Plus 2.1 and higher

Solution: Disable Adblock Plus and then immediately enable it again. No browser restart required.

Works again! Mozilla crashed earlier. That's why I restarted.

Thanks! Mike
