Dec 19, 2015 Update from Yosemite (10.10.5) to El Capitan (10.11.2) Thread starter Simpsonbear; Start date Dec 19, 2015; Tags el capitan issue Simpsonbear. Joined Nov 10, 2013. Apple removes the last macOS version when the new update is released. Because of problems with High Sierra, you can still download Sierra from Apple. You will need to find someone with a copy of El Capitan.
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.
Yosemite 10.11 Download
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.
Os Yosemite 10.11
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.
Yosemite 10.11 Update
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.
