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.
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.
I wish to download and install Firefox 52 ESR for a PC with Windows XP. But, I cannot download it on that WinXP PC. I must download it on another PC running Win 10. It should be an .exe (or somethng like that) file, which I can then transfer to the XP PC and run it to install FF 52 ESR.
If I try to download FF on the Win 10 PC, it downloads (I think) the version that is best for Win 10 PC. I do not see any place where I can specify that I want FF 52 ERS, and not the version for Win 10. That is the problem.
Please advise how I can do the above.
