Fixing Firefox

My Firefox has been acting up. It stopped remembering passwords and logging me into password protected sites like Facebook, Model Railroader, and this blog. Tried one thing and another thing. I just found a fix.
Firefox maintains for each user a "profile". Profile is a hard disk file folder that holds your bookmarks, your saved passwords, and a grunch of other stuff. Files in the profile can get corrupted and then Firefox starts doing weird things.
The Fix is to start up a pure clean profile. The only thing in your old profile that you care about is your book marks. So export your bookmarks to an html file and import that file into the new profile. Do this from within Firefox. Click on Bookmarks -> Organize Bookmarks and then click on "Import and Backup" tab. Select "export html" There is a "backup" option but that does something different and will not work here.
Exit Firefox and restart it from the "Run..." selection on the Start Menu. Enter
"firefox -ProfileManager" in the run box. This will present you with a little window with some choices in it. Pick "Create New Profile" and you are done. This starts up a new clean blank profile. All you need to do now, once you get back into Firefox proper, is import the bookmarks.html file that you created earlier.
The new clean profile lacks any saved passwords, so you will have to present your password to each website that needs a password. Keep a sharp eye on the Firefox window and you will see an inconspicuous gray bar appear briefly asking if you want to remember the just entered password. Click "yes" and Firefox will remember the password and present it automatically for you next time.
