How to fix the new Firefox tabbing style (3.6+)
Apparently, Mozilla adopted the way Opera handles tabs when you open links in a new tab. Quite frankly, I do not like it since I’ve been so used to the old style of opening new tabs towards the right, and it can get confusing sometimes.
Thankfully with a quick search, I found out through a Google Groups thread that you’re still able to use the old method without having to downgrade or use an extension. Thanks Larry and Dave!
Here’s how to do it:
Type “about:config” in the url bar and agree to the terms that you won’t break anything.
search for “browser.tabs.insertRelatedAfterCurrent”
double click to set it from “true” to “false”
and you’re all set to go!
