Firefox doesn’t respond when I start it. I went to the Firefox help page and it said the problem was that my profile should not be read-only. However, I can’t seem to change it. How do I change the profile from read-only?

    Make sure that you do not have read only file in your Firefox profile. The read-only attribute may have been set by restoring files from a CD or file protected media, and can cause numerous problems within your Firefox profile. Windows allows you to remove read-only attributes at the directory level for all subordinate folders and files.
