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

I've been using this for a long time. Glad to see this version that works in the new FF. Waiting for Toolbar Buttons to be updated to work in the new FF.

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"

Very useful. Mtks.
