Your Firefox profile cannot be loaded. It may be missing or inaccessible. [Fixed]
There are a few different ways to fix this issue. I will talk about what worked for me. Here is how it starts, you open Firefox only to experience a pop-up saying: Your Firefox profile cannot be loaded. It may be missing or inaccessible.
Here is how I fixed it on Windows 7 Home Premium.
Press the Windows Key + R and type %APPDATA%\Mozilla\Firefox into the Run box and hit enter. Delete your profiles.ini file. The next time you open Firefox a new profiles.ini file and a new default profile will be created. This fix may or may not work for you, but this is what worked for me. I hope this helps.
