Absolutely perfect. Not sure when exactly Firefox removed this functionality by default but missed it an absolute tonne and this adds it back without any issue :)

This doesn't seem to work on all webpages anymore. Any chance of a fix for that?
Or maybe it randomly stops working...

Thank you for this

it works great. the fact that firefox doesn't include such an option is dumb, but thanks.

EDIT! It started working all on its own, no idea what the issue was but now it's perfect. 5 stars, thanks!

(I saw lots of recent reviews saying it works and I didn't want to mess up the rating so that's why I did four stars)
I've installed the extension and even restarted Firefox and I can't get it to work. I do have previous pages that I can return to by pressing the usual back button. Any thoughts on how to get it working? I've just migrated from Chrome to Firefox and am trying to find a substitute for the extension I had there.

Lightweight and it works!
Would it be much trouble add a "Shift+Backspace" function for navigating forwards Mikko?

Simple and good.

just installed, tried backspace on a site with no text boxes and previous pages...did not work so i'm removing...went to a different page and it suddenly worked re-rated 5 stars!

I installed it and immediately was able to use the backspace key to go back a page. Works great!
