# Other Versions of 1Password

Starting in 1Password 3.6, the minimum system version required is Mac OS X 10.6 (Snow Leopard).

If you are on 10.4 or 10.5, you can download one of the versions below. While we are happy to help if you have problems using these other releases, new features will not be added so it is recommended you upgrade to a newer version of OS X as soon as possible.

## 1Password 3 for Mac OS X Leopard (10.5)

1Password 3.6 added support for OS X 10.7 (Lion), replacing OS X 10.5 (Leopard) support. The last supported version for Leopard is 1Password 3.5. Download.

## Firefox 3, 4, and 5

It’s really a good idea to upgrade to the latest Firefox version if at all possible but if you really need to stay on a previous version of Firefox, you can download the old 1Password extensions here:

- Firefox 3
- Firefox 4
- Firefox 5

Once downloaded, show the file in Finder and then drag and drop it onto an open Firefox window.

## Camino 2, Flock and Older Browsers

1Password 3.5 was the last version to support Camino 2 and Flock. Download

## 1Password 2 for Mac OS X Tiger (10.4)

1Password 2.12.1 was the last version to support Tiger. Download

Note that 1Password 2 is free for 1Password 3 owners. In other words, 1Password 3 licenses will work in 1Password 2.
