Firefox version 122.0 Mac: Sonoma 14.1.1 apple silicon The problem emerged about a little over a year ago (around September 2022). It started with an installation of firefox on another machine running BigSur, and I guess the problem got ported when I restored a time machine backup on this current machine. I attempted to troubleshoot the issue by following mozilla support and reddit threads but to no avail. I, at the time, settled on monthly time machine backups, but now finally decided to address it properly. Troubleshooting steps that I have followed: * going into the about:config page and changing the '''places.history.expiration.max_pages''' and '''places.history.expiration.transient_current_max_pages''' to 2147483647 then to 999999 after reading about how a value too high might be ignored (both values didn't seem to change anything) * going into the about:config page and changing the '''places.history.expiration.transient_optimal_database_size''' to 85534800 * removing the add-on/extension manager as seeing that it might remove history for some reason (from a [[https://support.mozilla.org/mk/questions/1384652|similar thread]] by IceTemple) * In the privacy and security tab, history is set to '''Firefox will use custom settings for history''' Things I suspect might be the problem: * I originally used the Chinese version of firefox (downloaded from the .cn website) and reinstalled the international version (from .com) after getting annoyed by the built-in ads. For convenience sake, I ported the profile folder over which might have carry the problem over. That being said, I don't think this problem existed when I just started using firefox but appeared awhile later. * result of an update, don't know which though * certain extensions (I haven't went through them individually since I installed a lot) My questions: # How to stop Firefox from doing this ever again? # Alternatives of storing history if nothing works # Why did my troubleshooting steps not work? Is there something wrong with my version of firefox that prevented the about:config changes from working? # If I have to resort to backing up the places.sqlite history file, how do I restore/reintegrate them with current history file? English isn't my first language so I apologize for any confusion that may arise due to how I articulate. Any help is much appreciated
