Though for the full value I personally really also need some sort of interface that can show individual page visits in order to answer the question "What other pages did I visit at that point in time?" (sometimes I don't remember the right keywords to find a certain page again, but only some other page I visited during the same browsing session). The built-in history view is only of limited value here, because it always only shows the most-recent visit, so as soon as you visit a page again, it moves to the front of the list again and loses its original place and history context.
As usual, there used to be an add-on for that, which was subsequently broken by the move to webextensions (and even if somebody wanted to rewrite it, the webextension API doesn't cater for its full functionality). Thankfully some kind soul has maintained a version hacked to still work even on a current Firefox (https://github.com/xiaoxiaoflood/firefox-scripts/tree/master...).
