I have just downloaded & am running the latest version of Firefox.

In my 'Downloads' folder there are now four versions of the Firefox Setup: three copies of 43.0.1. and one copy of the latest, 51.0.1.

Which of these can I safely delete?

Many thanks

Once you have installed Firefox then you can delete to setup file you used to install Firefox. If you would need to reinstall Firefox then you can consider to keep the setup file of the current release.

Firefox is installed in the Firefox program folder and your personal data is stored elsewhere in the Firefox profile folder, so you won't lose any personal data.
