I'd like to know how long Firefox will record and save history in this folder. It goes all the way back to December, 2015 and would like to continue as long as possible without loosing any history from that month to the present.

Thank you

Current Firefox versions keep a maximum number of visited page and do not have a time limit for the history. Firefox determines automatically how many pages can be kept without affecting the performance.

You can see the current value of this maximum as the value of the read-only pref places.history.expiration.transient_current_max_pages on the about:config page.

Note that you can do a copy and paste of history items to a bookmarks folder.

See Marco Bonardo's blog about this subject:

I am seeing in about:config - status: user set, type: integer and value: 50262. Is that info any indication of how much longer or whatever about the history that will continue without loosing any history from Dec. 2015 till present?

Thank you

This pref is usually well over 100000. I see:

  • places.history.expiration.transient_current_max_pages = 104506

If yours is only half of that value then you either have a slow computer or are low on memory or something else is wrong that makes think that you can't handle more history.

I noticed this as well...my Library currently stops in December 2015 (five {5} or so months ago) so I checked places.history.expiration.transient_current_max_pages in about:config and saw 53661.

When I tried to "Modify" it to 100000, it wouldn't change at all...is that supposed to happen? I thought we could modify the value ourselves, as it's "user set".

Thanks, Bram Weiser

places.history.expiration.transient_current_max_pages is a read-only pref and can't be modified.

Oh, sorry, cor-el (and hi, again). I missed in the "Helpful Reply" where you did say "read only".

So, just so I'm (and others are) clear, this is a completely automated process to determine that figure, and there's NO way for a person (like me) to make that maximum figure (or anything like it) any higher? Is that correct? We're "stuck" with whatever Firefox itself determined the maximum "size/duration" of the history would be?

Thanks again, Bram Weiser

You can create a new integer pref named places.history.expiration.max_pages if you want to adjust the automatically calculates number of pages to keep as you can read in that blog article. Be cautious though with modifying the value of this pref.

Thanks again, cor-el.

I read that "bonardo" page but, forgive me, didn't quite see how to manage the number of these pages with these prefs.

So, if I add a pref called "places.history.expiration.max_pages" (as you spoke of in your previous response), and set it to, say, 100,000, things should be OK? (That would be a little less than double what I saw at the other read-only pref.)

Also, you mention specifically that I should be careful with this pref. Can you please elaborate on that concern?

Thanks again, Bram Weiser
