I cannot access any settings and have tried reinstalling several times.

I changed settings on history and cookies prior to restarting because Firefox was sooooo slow. I have tried doing restarts, reinstalls, repairs to HD, etc. Nothing is working and I have a lot of saved information on Firefox that I can no longer access to even backup. What shall I do?

Thank you in advance for the help.

Rename the C:\Program Files (x86)\Mozilla Firefox folder.

Then

Download Firefox Full Installer All languages {web link}

If there are still issues, rename the user profile folder.
