Restrict history to one hour or 100 pages
I try to restrict my Firefox history so everything what is older than one hour gets deleted automatically. If this is not possible I would also use something like same only the last 100 pages and delete the oldest page if the 100 pages are reached. I tried to change the places.history.expiration.max_pages variable in the about:config tab to 100 or lower but Firefox still saves everything. Every help is appreciated thanks you!

You can look at the comments in the source code to see how this works:
Thank you for your answer. Unfortunately I only have very small knowledge in JavaScript. Could you tell me what lines I have to change to disable the automatic maximum page calculation based on the hardware and replace it with a fixed number of pages? I also wonder how often this script is running for example if the delete to old entry script only run once a day it is not possible to delete everything older than an hour. But I am sure I could change the code for the maximum page calculation I would appreciate help with that.
I see at line 78 that only history older than 7 days is removed, so that is likely why you do not see your history removed.
// Finds visits to be expired when history is over the unique pages limit, // otherwise will return nothing. // This explicitly excludes any visits added in the last 7 days, to protect // users with thousands of bookmarks from constantly losing history.
You would have to remove this history yourself or possibly use Private Browsing mode to prevent history from being kept at all.
