How can I make Firefox preserve history forever?
I currently have the latest version of Firefox which I recently changed to. On previous versions it used to be possible by changing certain settings in about:config to make Firefox keep history longer than the default. I searched "history" though and I can't find that particular setting. It's really important for my business that Firefox doesn't delete my history. My system is able to support a larger history file. Thanks.
