Firefox is slowly deleted my browser history older than 6 months. How do I keep history forever?

more options

I just noticed that my browser history older than 6 months is slowly being deleted day by day. How do I prevent this from happening? This has only started happening recently. I have my settings as "Remember history". I want to keep all my history forever. Are there any configurations I can make to achieve this?


Thanks for your time.

Firefox automatically calculates how many pages to keep without affecting performance and saves that value in the transient_max_pages pref.

You can create a max_pages pref to override that current maximum, but it is better to leave those prefs at their default.

You can see the current value via the read-only pref places.history.expiration.transient_max_pages on the about:config page.

The value is set at 18945. I am no where near this value, and I am not adding a significant amount of pages per day, yet firefox still deletes dozens (hundreds?) of pages per day. Does this have to do with "days" passed rather?

Someone please advise with a solution. I am willing to override any default.
