I use an old one called "get mail". It adds entries to tools but I can create an icon in the bookmarks toolbar. From there I can click to read or write email and it brings up T-bird.
Just to be clear, I recently installed Thunderbird. I set it as the default email program. I did the "file" association thing in Set Program access and computer/defaults/custom. Its the only email program. It's up and running. Everything works. I'm getting my emails. I went to the Firefox menu and added the "email" link to the 'browser'. However, when you click on "this" link, it opens the part of the program where your going to sent a new message. It doesn't open the "email message" center so that you can see if you have any new emails and then send any new messages if you want.
When I had windows xp, the "icon for outlook express in the browser took you to the message center. How do I do the same thing in Firefox. Currently, I have the Thunderbird icon pinned to my taskbar and that's how I open the "message" center.
Dell Inspiron 3647 computer, 3GHz, 4 G Ram, all windows updates... Firefox is my default browser...Windows 8.1
Thanks in advance for any "link" or suggestions,
