My computer updated to V55 this morning. Since doing so I have lost all cookies, all bookmarks and all saved usernames/passwords.

Not Impressed as this was an auto update!

How do i recover this data as it is effecting my work! spent over two and ahalf hours trying to restore and nothing is working!

Note: V55 has been giving users problems. Reinstall v54.

If you still want to downgrade, look under; I still want to downgrade. Click the Directory of other versions and languages link. Look for the directory of the version that you want. But, remember that old versions may have security issues.
