Is this a addon? Or the password manager built-in? If its the first, you need to report it to the addon developer.

It is an Add on. However, I don't think it's a problem with the Add on. The Add on (Password Box works fine on Chrome & Firefox on my PC. Just not on the Firefox on my Mac.

What is the setting of the about:newtab page if you check the browser.newtab.url pref on the about:config page?

See this article about the New Tab page (about:newtab):

• https://support.mozilla.org/kb/new-tab-page-show-hide-and-customize-top-sites

I would like to un-install the Password Box completely.

I tried to use Regedit, and deleted the listings, but that did not work. I saw a posting somewhere stating that if you Un-Install Firefox and reinstall it that would work, but it did not.

Any suggestions out there?

Hi MagicMan_35, did you try this support article from the company: https://www.passwordbox.com/uninstall

Does that leave traces behind that need to be cleaned up?

Hi all,

Thanks for the reply. My trouble is that it does not show up in those windows. I am fearful that this is a virus, malware, or other vicious attack

Any other thoughts would be welcome.

If the problem is only with new tabs (not new windows), there's a separate, hidden setting for what appears on new tabs.

(1) In a new tab (or new window or same tab...), type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste newtab and pause while the list is filtered

(3) Double-click the browser.newtab.url preference and enter your preferred page:

• Page thumbnails (default) => about:newtab
• Blank tab => about:blank
• Built-in Firefox home page => about:home
• Any other page => full URL to the page

Press Ctrl+t to open a new tab and verify that it worked. Fixed?

Two gotchas:

• If Firefox ignores the setting, one of your extensions may be overriding it. You can review, disable, and/or remove extensions on the add-ons page:
  
  Tools menu > Add-ons > in the left column click Extensions

• If the change works but at the next startup is back to Google, you might have a user.js file in your personal Firefox settings folder (your Firefox profile folder). This article describes how to track down and remove the file: How to fix preferences that won't save.

Any luck?
