FF 71. Cannot change value in setting places.history.expiration.transient_current_max_pages

In about:config I set the value to 2147483647 on one PC and 999999999 on another. Now it's not possible to change the numbers. I see this setting in the prefs.js file, but have not changed it there yet. Why is that?

Am I generally picking the right settings so that, in fact, the browser never deletes the pages I visited? Now I still use FF 56.0.2 and the places.sqlite file is 300 MB in size, FF 71 happily accepted this file and my history remained in place.

Note that places.history.expiration.transient_current_max_pages is a read-only preference.

Like you posted, you have to create a new Integer pref named places.history.expiration.max_pages if you want to modify the automatically calculates number of pages as shown in places.history.expiration.transient_current_max_pages.
