How to Make a Firefox Screen Grab Without Any Tools
Firefox is capable of taking full-scale screenshots by default, even without plugins.
1. Once your page is fully loaded, right-click it and select "Take a screenshot". There’s a hotkey both on Windows and on Mac - Command(Ctrl) + Shift + S.
2. From there on, there are many options, such as clicking-and-dragging (to select an area), clicking an HTML element, or saving the visible area. You need to choose the option to "Save full page".
3. Afterwards, copy your Firefox screenshot to the clipboard or download it.

Comparium is quite flexible. It offers several methods of comparison that give you a better look on the differences between pages.

This is exclusively a paid service, but you get a whole lot of options. Most importantly, you can switch between platforms on which the site is tested. But it doesn’t end there: you can adjust other minutia, such as system version and screen resolution. All in all, it’s a pretty serious tool that may interest well-financed and technically advanced users.

However, its use is heavily restricted: a 30-minute demo is all you can get before having to buy it and install software on your system. It’s also worth mentioning that you need to sign in before you can even access the demo.
