This maybe the issue Firefox Homepage 2.57 Extension (cehomepage@mozillaonline.com) No idea, never seen it before, can not find it. Run the scans though

No new:tab for now....who knows. This may or may not work : https://addons.mozilla.org/en-US/firefox/addon/new-tab-override/

Please let us know if this solved your issue or if need further assistance.

While I don't think it is caused by any malware, since I am redirected to a site seems related to mozilla. I guess that is done by firefox itself. Maybe the malware is a part of China version firefox : ( The new tab override addon is great, but I just want to use default about:newtab. I can't do this through the addon

Yes we know. And you need to check for malware. That should not be happening. Mozilla does not redirect people to China.

See if this helps with getting video card drivers https://www.intel.com/content/www/us/en/support/detect.html

What do you think about disabling this extension: Firefox Homepage?

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. If in doubt, disable.

Any improvement?

Thanks for all you guys help! It is caused by the firefox homepage extension. I didn't even notice I have this.
