Hi Kulta,

Have you looked at the Home page with pipe character opens extra tabs when Firefox starts Knowledge Base article? That should resolve your issue for you.

Just out of curiosity, what are the pages that open? If it is the "Welcome to Firefox" page, you should look at this article about that specific issue and the article Preferences not saved. These should give you all the information you need!

If that doesn't work:

  1. Type about:config in the address bar
  2. Click I'll be careful, I promise if prompted
  3. In the Filter input field type startup
  4. Double click on startup.homepage_override_url
  5. Delete the text string and click OK
  6. Close Firefox and reopen the window to verify that it has worked.

Hopefully this helps!

Do you get three tabs in the same window or do you get three windows with each a tab?

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the sessionstore.js [2] file and possible sessionstore-##.js [3] files with a number and sessionstore.bak in the Firefox Profile Folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

Click on the Firefox button then click Options > Options.

Look at the screenshot below:

Do you have these | symbols in your homepage websites? If yes, delete each one and the websites that are next to it. Do not leave any of these | behind. Delete them all.

The bar symbol, | , adds a new tab. Even if there is no website listed after it.
For example:||
This has 2 bars so 2 blank tabs will open and 1 tab will open with google.
