All of a sudden I have to log in to all the common websites I use such as Yahoo mail. It could have been something I changed but I don't know what. From what I understand it may have something to do with the setting Cookies and site data. I think that if the box that says "delete cookies and site data when Firefox is closed" is checked then the log ins will not be remembered. The problem I have is that particular setting is ticked and it is shaded and I cant uncheck it. Can someone provide a simple solution please?

You may be in Private Browsing mode or told Firefox not to remember.

Type about:preferences#privacy<enter> in the address bar. The button next to History, select Use Custom Settings.

Turn off Always Use Private Browsing Mode Turn on Remember My Browsing And Download History At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on ONLY Cache and Form And Search History leaving the others off.


Macs: Make sure you install Firefox properly and that you do not run Firefox from within the DMG (Disk Images) file. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac
