I want to permanently unpin and remove a tab, but the pinned tab keeps opening whenever I restart Firefox.

I accidentally pinned a tab. Now every time I open Firefox it is there, even if I unpin and close, or just close the tab and restart the browser.

Chosen solution

Changes made manually on the about:newtab page are stored in the browser.newtabpage.pinned (default = [null]) and browser.newtabpage.blocked prefs that you can check/modify on the about:config page

This somehow fixed itself after a couple of days of unpinning. I'm not sure what I did but if it comes back I will try your method. I just had a look in the about:config page and couldn't find either browser.newtabpage.pinned, nor browser.newtabpage.blocked, but that may be because I no longer have anything pinned. Thank you.

Yes, those prefs are only there if you have either pinned or blocked an item on the about:newtab page.

If it happens again and you do not keep changes after a restart then see:
