Hi. I'm using Firefox 16.0 and I have a PC that runs Windows Vista. I'm having trouble with my computer, and I'm going to need to re-install windows. I really do not want to lose my web history from these past few months, and I'm not sure how to back it up, I've only been able to back-up my bookmarks. If someone could tell me how to back-up my web history it would be greatly appreciated, thank you!
