I need to be able to download an earlier version of Firefox (my current install is V55.0.2) Running Windows 10 64 bit I have a particular piece of software which will not run on any version of Firefox later than V51.

Starting with Firefox version 49, Firefox requires Mac OS X 10.9 (Mavericks) or higher. Visit this Apple Support page to find your Mac OS version.

If you're using an outdated version of Firefox on Mac OS X 10.8 (Mountain Lion) or earlier, the only way you can update Firefox to a secure version is to upgrade your Mac OS to a version that Apple supports. Visit this Apple Support page to learn more about upgrading your Mac.

Note: If you have Mac OS X 10.7 (Lion) or 10.6 (Snow Leopard), you will need to download OS X El Capitan before you can upgrade to the latest Mac OS.

While insecure versions of Firefox will continue to work on OS X 10.8 and earlier, using an up-to-date version of Firefox on a supported version of Mac OS will provide you with the best and safest user experience.

Mozilla Firefox For Windows 10

Compiled with Clang-cl on Windows
Disabled Encrypted Media Extensions (EME)
Disabled Web Runtime (deprecated as of 2015)
Removed Pocket completely
Removed all telemetry/data collection being sent back to Mozilla
Disabled the 64-Bit NPAPI white-list so that the user can decide what plugins they can run (doesn’t make sense for Mozilla to do this as most of their user base probably aren’t technically proficient), but it’s something Waterfox users are capable of handling.
I’ve also allowed unsigned extensions to run as well as there are still some old extensions people like to use (it’s disabled by Mozilla for the same reason as above)
Windows XP 64-Bit support (issues since v46)
Removal of Sponsored Tiles on New Tab Page
Removal of Snippets from Home Page

N.B.

When using a profile shared by Firefox, sponsored tile and snippet URLs may overwrite default Waterfox settings, enabling them again
Automatic updates will be delayed by 24 hours to make sure there aren’t any pressing issues before seeding to everyone.
