Tab Grouping in Firefox

If you are like me and find that you are finding it hard to get used to Firefox grouping child tabs opened from their parent tabs next to the parent (opening up a tab in the background next to the tab you are currently browsing) and want it to go back to the old way of opening the new tab at the end of the list of tabs opened, follow the steps below to get that method back

1. Type "about:config" in the Firefox address bar. You'll get a warning that you are about to void your warranty. Just click the "I'll be careful, I promise" button, and you'll see a list of all the browser settings that can be changed.

2. In the text box labeled "Filter:", type "tabs.insertRelatedAfterCurrent"; you should see just one entry below. In the column marked "Value," double-click on the word "true" to change it to "false."

That's it, close that tab and you're done.
