The Library window collapses every visit to a particular URL to one entry, listed under the date/time of the latest visit.

Firefox still has the data on earlier visits so you can use a separate tool to extract the full list. If you are mostly interested in a daily list, this extension has a nice layout. However, if you need to search across a lot of dates, it doesn't show as much detail:

If you need to track history per tab or from site to site, I think there probably are other extensions for that, but I've never tried them.

Hello. Thank you for advice.

But since

>The Library window collapses every visit to a particular URL to one entry, listed under the date/time of the latest visit.

even this plugin has the same issue (since database is the same).

I mean you if open something and then want to find when you opened it before - you can't.

What I want to achieve - is to have history as history and not as database of unique URLs I visited (1 timestamp per 1 URL).

But I think it is only possible by changing Firefox code, not by plugins.

No, Firefox has the data on all the visits, but the Library window does not show all the data.

(I use a Windows program named MzHistoryView to export a zillion-page .html file of my history every month so I've definitely seen it. I don't know of a similar program for Mac.)

Interesting. Because I tested the plugin you suggested and it has the same issue. I opened history in it -> found a link from Monday -> opened it -> refreshed history -> link *moved* to Wednesday.

Maybe Firefox on macos has different implementation of history. Or I need to try my luck with different plugin.

Yes, I guess that extension is also de-duplicating the history. I don't know whether the author will consider providing an option for that.
