How do I keep the new tab page thumbnails visible even after deleting my browser history?
Every time I delete my browser history, I notice thumbnails of my pinned sites on the new tab page disappear. Is there a way around that; or something that can be done so it doesn't occur in future versions of Firefox?
If you are clearing your history this will naturally happen. You can try to make sure you don't clear your cache, this may help. The thumbnails on the New Tab page are missing - how to get them back
the option to clear my cache isn't selected; and it's the same in the options menu.
Current Firefox versions use a separate thumbnails folder to store those images, so clearing the cache should no longer make them disappear.
However clearing the history will prevent any slots from retaining the URL.
If you want specific pages to show on the about:newtab page then you can drag a bookmark or history link into a slot to pin a web page.
Do any of the slots have an URL displayed under the image placeholder?
They have the name of the site underneath the picture. This problem is with the pinned sites; there are no images for several of them.
