Firefox will not remember my cookies between sessions fix
I had a weird problem with Firefox 3.0 - every time I restarted it would loose the log-ins to websites, and the configuration of my tiddly-wiki. I figured out it wasn't saving cookies. I read some Mozilla web pages and found that cookies are stored in my Mozilla profile, in cookies.sqlite. Explorer said the 160 Kb file hadn't been modified since January! Being the skeptic I am, I closed Firefox and deleted cookies.sqlite. Problem fixed - Firefox re-created a 2 Kb file, and my cookies are now saved between sessions.
