Re: How do i save my favorite websites to homepage?
You can change the order of the boxes on the about:newtab page and drag them to a different position to pin them to that position or you can remove them by clicking the close X of an item to block them.
You can drag a bookmark or history item and drop them in a slot on the about:newtab page to pin them.
Changes manually made on the about:newtab page are stored in the chromeappsstore.sqlite file in the Firefox Profile Folder under the pinnedLinks key and blockedLinks key.
