Saved logins are not visible after entering the master password, even though Firefox is still populating the credentials to log in to web sites. The saved logins dialog/table does not display any sites or credentials.

Thanks. Malwarebytes found Trojan.Poweliks.B. After removal and restart the problem in Firefox was not resolved. I did a system restore to a March 7th restore point. After that I was able to see the credentials. I then checked the version of Firefox and it automatically installed version 45. Then I was no longer able to see the credentials. I decided to try to reinstall Firefox and went to the Firefox website, which offered to do a refresh of Firefox. I let that run. After the refresh I was able to see the credentials but now found that none of the add-ons I use was reinstalled. I installed the Master Password+ add-on and then found that I again could not see the passwords. I uninstalled Master Password+ and was then able to see the passwords.

In summary, it appears that Master Password+ conflicts with Firefox v 45 by not displaying the credentials in Saved Logins. The credentials are not deleted, they are just not displayed.
