I recently lost all of my bookmarks and need to recover them from a week ago, how?
Last wednesday I lost all of my bookmarks. I assumed that they were saved in Windows live log in for msn which is my homepage. I also lost my homepage and windows/msn account. How do I restore my bookmarks or my system to a point that everything worked?
Note that your System Details List shows that you have a user.js file in the profile folder to initialize some prefs on each start of Firefox.
The user.js file is only present if you or other software has created it, so normally it wouldn't be there.
You should check its content with a plain text editor if you didn't create this file yourself.
The user.js file is read each time you start Firefox and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.
