Firefox version 78 is the last supported Firefox version for Mac users of OS X 10.9 Mavericks, OS X 10.10 Yosemite and OS X 10.11 El Capitan. These users will be moved to the Firefox Extended Support Release (ESR) channel by an application update. This will provide security updates until the next ESR update in July 2021, after which the affected users will no longer receive security updates.
- However, in the case of Mac computers, Mac OS EL Capitan still has it all to be in the category of best Mac operating system. The version before Mac OS EL Capitan was Mac OS X 10.10 Yosemite. Later Apple Succeeded Mac OS EL Capitan 10.11 with the new operating system that was Mac OS 10.12 Sierra. The Mac OS EL Capitan has very good performance.

Unless you downloaded the initial release of El Capitan (10.11) and saved the Install OS X El Capitan.app file, you won't be able to download it from Apple. Ie 11 for mac download. All that is available is the current version 10.11.1.
While Apple does not have a public policy governing security updates for older OS X releases, their ongoing practice has been to support the most recent three releases. The last security update applicable to OS X 10.11 was made available in July 2018. Unsupported operating systems do not receive security updates, have known exploits and can be dangerous to use, which makes it difficult to maintain Firefox on those versions.
Up until July 2021, we will be updating affected users with critical security updates through the Firefox ESR channel to help retain the best possible security. After this, no security updates will be provided.

If you want to keep your Firefox version up to date, you will need to upgrade your operating system to macOS 10.12 or higher. Older versions that are not supported by Apple are unreliable and unsafe to use, which also makes it difficult to maintain Firefox on those versions.
