Firefox doesn't show/display my addressbook within my hotmail account anymore. Cookies/Cashe has been emptied already, result is the same.

Question

Firefox doesn't show/display/load my addressbook within my hotmail account anymore, it worked previously well, so has nothing to do with the change from hotmail to outlook. Since a week or so, I realized a slowness in loading my recently used addresses with opening a new e-mail, but it was still working from time to time. For a few days, it has been stopped working, complete addressbook doesn't load anymore, just displays the load circle in the middle of the screen, apart from that I have only a white page. Cache and Cookies already emptied/deleted, result is the same. No settings have been changed, but have the same issue with Internet Explorer, but it's working with Chrome. For testing, I deactivated my firewall and anti virus (Comodo), but the result was still the same. I would appreciate if I could get it working again here. Every suggestion is welcome here

Answer 1

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Do a malware check with some malware scanning programs on the Windows computer.<br />
Please scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.
