I have 2 sites that I have cleared history on but they both still show up on the top sites section and I can not remove them. Help

Chosen solution

Do you mean in a tile on the about:newtab page?

You can delete the thumbnails folder in the parent location used for the disk cache to clear all thumbnails you see on the about:newtab page. You can find the location of the disk cache on the about:cache page. You can open "about:" pages via the location/address bar


Do these tiles open that specific page if you click them?

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, history, cookies, passwords, cache, and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of the involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.


You can change the order of the boxes on the about:newtab page and drag an item to a different tile to pin it to that position or you can remove a website by clicking the close X to block that URL. You can drag a bookmark or history item from the sidebar and drop it in a tile on the about:newtab page to pin this item and have your own favorites sites present.

Changes made manually on the about:newtab page are stored in prefs that you can find on the about:config page.

  • browser.newtabpage.pinned stores websites that you have pinned to a tile.
  • browser.newtabpage.blocked stores websites that you have removed by clicking the X button in a tile.
