I saw the most recent review was 5* but it seems the 3 year old reviews are still accurate. The button only works as a regular back button for me

I loved this :-) when it was working in older Firefox or Waterfox versions (WF Classic), but sadly it doesn't work in Firefox fork Waterfox (G-3, neither did it in Waterfox Current). Just now it works like normal back one page arrow - one star only this far.

Doesn't work. Behaves just like a regular back button

This is what I want! It'll be perfect if you add key shortcuts

The point of a button like this, for me, is to go back to the first page of the *domain* one started browsing. This button takes me back to the speed dial used to select the domain. Not useful at all.

It works most of the times, but sometimes it only goes back one page. For example, if you are using Google Maps, this button only goes back one page, not to your startup page. I still have to click on the back arrow pull-down to go back all the way. At other times, it does nothing (for example, the page you are reading now, https://addons.mozilla.org/en-US/firefox/addon/snap-back-button/reviews/ -- doesn't go back at all).

Works as advertised. Only issue is the title in the Add-ons Manager has a typo: Snatp Back.

might be super-usefull for malicious code.
use-case: webpage1 --> user goes to --> webpage2 (with malicious code) --> which redirects them to --> maliciouswebpage (which prevents going back to "webpage1" or "2". time will show, but i think other user-cases are also possible.
follows a philosophy "to do 1 thing, and to do it well"

a good feature option would be if there is no back history, close tab instead

Very useful. Mtks.
