This may not be the best place to look for help, but I figured I'd give it a try.

My Firefox seems to be forgetting cookies.  I used to be able to log on to a site and stay logged on no matter how many times I closed Firefox or shut down my computer.  Yesterday, a thunderstorm was heading my way and knocked the power out for a second while I was on the computer.  That's happened before, but ever since it happened this time, I can't stay logged on to sites.  Every time I open up my browser i have to log in to any site I go to.  None of the settings seem to have changed either.

Does anybody have a clue what could have happened?  I'm sure it's related to the power going out, but I don't know how to fix the problem.
