everytime i open new tab, the tab opens, but a duplicate window opens in tray with duplicates of my window and all my currently open tabs.
for several years, after uninstalling and reinstalling, I cannot open a new tab without a complete duplicate being created with all the same open tabs. Example .. I have a window with four tabs open. In my tray, i have 4 windows, all with the same 4 tabs. uugh!

Could you check to see whether you have a particular box checked in the Options dialog:
"3-bar" menu button (or Tools menu) > Options > Tabs
If "Show tab previews in the Windows taskbar" is turned on, instead of having one entry per window, you get one entry per tab. Uncheck that to turn it off.

By the way, your "More System Details" shows that you have a user.js file. Firefox reads this file at startup and uses it to override the preferences you had set during your previous session. If you did not create the file, you may want to review, edit, or delete it. This article has more on tracking that down: How to fix preferences that won't save.
Thank you jscher2000!. You have no idea how I suffered from this annoyance. Not to mention all the memory utilization that continually slowed down this computer. Thank you again. Did i say thank you yet.. Well "Thank You" :) Joe
