I lost Firefox for no apparent reason. I deleted the program and attempted to reinstall and download. Received an error message that read "Your firefox profile cannot be loaded. It may be missing or inaccessible." At the same time, I lost Picasa and all my photos. When I tried to reinstall Picasa, I received the same message about Firefox. Can someone please help. It's driving me nuts.

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
