Thank you for sharing your Add-ons list. I think it's the one called "Maps" that is causing this.

You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either:

• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons
• type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Extensions. Then cast a critical eye over the list on the right side. Any extensions that Firefox installs on its own are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything suspicious? If in doubt, disable (or remove).

Often a link will appear above at least one disabled extension to restart Firefox before the change takes effect. You can complete your work on the tab and click one of the links as the last step.

Any improvement?

Hi   !

That hdirectionsandmap.com is a browser hijacker, which you will of course have to get rid of.

After you have done as suggested by jscher2000 :

Also look in :   Advanced => Network tab => Under : 'Offline Web Content and User Data'

Do the same in Windows' Control Panel => Programs.

If you find anything that you don't trust : remove it.

However :   most malware will be 'hiding' somewhere , so let's run malware scans :

Further information can be found in this article :

Run most or all of the listed malware scanners.
They all work differently   -   what one program doesn't pick up, the other might.
