• Make sure that you do not use Delete browsing, search and download history on Firefox to clear the Browsing History.
• Make sure that the History is set to at least 1 day: Tools > Options > Privacy > History: "Remember visited pages for at least"
• Make sure that you do not start Firefox in Private Browsing mode (Tools > Stop Private Browsing is grayed, see Private Browsing - Use Firefox without saving history)
• To see History and Cookie settings in Tools > Options > Privacy, choose the setting "Firefox will: Use custom settings for history"

You can look at these prefs on the about:config page.

• http://kb.mozillazine.org/browser.history_expire_days (180) (also affects saved form data)
• http://kb.mozillazine.org/browser.history_expire_days_min (90)

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

Thanks for your reply. My settings are OK. So far, it looks to be ONLY a certain site I use all the time. Something must have changed somewhere because at one time it did remember. Try it and see if it works for you. I have this problem on both computers, one was just clean installed 3 days ago.

PS you have to completely close FF.

Do you mean the history as you see it in the History sidebar or Library or history as in marking visited links with a visited color?
