Firefox opening a new browser/window

more options

I have Firefox pinned to my taskbar. This is how I open Firefox. It has Yahoo as my homepage, all my bookmarks and add-ons.

I also have an icon on my desktop. When I open that it does not have Yahoo as my homepage, my bookmarks and the same the add-ons.

When I click a link in a word doc or something outside of the opened browser, from my taskbar, a new browser/window opens. It goes to the site fine, but again it goes to new browser/window.

In both the above instances you will see an extra Firefox icon in the taskbar. The one on the right is the new browser/window.

I also have attached pics of what is occurring with each of the icons.

So, what gives and how to fix it?

Thank you, Irv

Hi Irv, you definitely have multiple Firefox profiles, but what I wonder is whether you might have multiple installations of Firefox.

In each of the different windows, could you call up the Troubleshooting Information page. Either:

  • "3-bar" menu button > "?" Help > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

In the first table on the page, please compare:

(1) Application Binary row

Where is your main installation and where is the other one? For example:

  • Current 64-bit program folder: C:\Program Files\Mozilla Firefox\firefox.exe
  • Legacy 32-bit program folder: C:\Program Files (x86)\Mozilla Firefox\firefox.exe

Do you have multiple installations?

(2) Profile Folder row

The part after the last . is the most interesting part. Please make a note of the name of your main profile for future reference.
