Amazon won't appear as tile on "New Tab"
I like the tile feature on new tab pages. For a long time I've had Amazon on there because I use it a lot. It vanished a couple of weeks ago. The browser is set to "show your top sites." I have logged into Amazon twenty times with zero results. Firefox creates a tile for my last site borrowed - but I erase them. At present I have an empty tile slot - which I usually do. If I log on to any page (I think) a tile will appear immediately - unless it's Amazon which won't load at all. Any suggestions welcome.

Possibly Amazon got on the block list, which occurs if you click the "X" on the upper right corner of the tile, or perhaps in other undocumented ways I don't know about.
To test that theory, you could (temporarily) remove the block list as follows and see whether Amazon returns:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.
(2) In the search box above the list, type or paste newtab and pause while the list is filtered
(3) Double-click the browser.newtabpage.blocked preference and if you want to preserve the block list, copy it out to a Notepad document or other plain text editor (something that won't try to reformat or interpret the data). Then cancel the edit, right-click the preference, and Reset.
Does Amazon reappear?
As you can see from the naming in the blocklist, it's difficult to figure out which one you would want to remove to restore any specific site. If someone else knows how to figure that out, then you wouldn't have to rebuild your block list from scratch...
If you drag a link or tab of a blocked site to a tile then that should remove the block.
