When my computer starts up and I open Firefox, Firefox closes automatically for no apparent reason. But when I open Firefox again, it's perfectly fine.

This only happens when I startup up my computer and open Firefox immediately. The browser would stay open for a couple of seconds and then it would close unexpectedly. Once I open Firefox once again, it seems to be perfectly fine and stays open. It doesn't give me any crash report as to any reason my browser closes unexpectedly previously. Can anyone help?
