I use Firefox on all my computers and phone, because its ability to save my browsing history and sync across devices has been unparalleled. This is invaluable because a certain website I frequent has a nasty habit of eliminating and locking its pages. (I’ve asked them about it and they plan to continue doing this.) Without the exact link and all the metadata from my browsing history, I cannot retrieve those pages. This past weekend when I went to recover a page, I discovered that FireFox has only six months of my history, not the many years I expected. I checked my pre-update profile, and it had no history either. I have some computers that have been offline for a few months so maybe they have versions old enough to still have my history. How do I get my history back and how do I avoid FF destroying my history without my consent in the future?
