No, I have no intention to rewrite the history.back() button.
Lots of browsing people while browsing go to a site not by opening a new tab, but by using the same tab again.
Then after a lot of internal tabs it takes time to return to the entering external domain.
In the past Firefox used to have a fastforward and fastbackward button for this purpose.
Experienced browsers like you use browsing history, but for inexperienced users, like most of my readers, a button back to the domain where they came from is quite useful. Instead of x times using the back button.
