Hello,

First try restore your new tab, go to about:config search for browser.newtab.url change its value to about:newtab, then restart firefox, verify if your new tab page return to default.

• about:config

Avast search page still comes up when you hit +New tab

I am sorry it is AVG search page

In safe mode the page also appears?

• Firefox in safe mode

yes AVG is still there

Try use this addon to reset the search page:

• https://addons.mozilla.org/pt-BR/firefox/addon/searchreset/

ok I have it back now... But all the sites I had pinned are gone. Is there any way to restore them?

Did you set Firefox to remember the history?

Try restore your last session:

• How do I restore my tabs from last time?

Or try go to your profile backup it and create a new one then restore the data profile:

• Profiles
• Create a new profile

On about:config window, how do I change the value to about:newtab?
