A menu box will come up with "History" as a choce. Click on it.
Another menu box will open with Most current-used links. At the bottom is a choice "Show All History." Click on it."
Another menu box will open on the left side of your screen with "Library" on the title bar. The box has two panes. On the left pane is a choice for "Last Seven Days." Click on it.
Then in the right pane, all the links you used in the last seven days will appear.
You can link to any of these entries.
The choice in the left hand pane also allows you to get to any of your Bookmarks.
**********
I used CCleaner within the last seven days, and it removed all the history entries accessible that drop down when you click on the down arrow that is within the address box, but it does not eras the links available from the Firefox procedure above.
I have auto delete of History.
