Win7 gets security updates until somewhere in 2020. After that point, anyone still using 7 will be better off upgrading to 8/8.1/10. Firefox 56 is not an ESR.

Win7 gets security updates until somewhere in 2020. After that point, anyone still using 7 will be better off upgrading to 8/8.1/10. Firefox 56 is not an ESR. It does not get security patches. From a quick look, there are public CVEs[0] that allow for ROP code execution almost effortlessly. Security was always one of the big reasons behind keeping browsers up to date (the other reason being propagating new standard faster). Besides, I wasn’t suggesting updating to latest firefox. I specifically mentioned pale moon and basilisk because they support old style extensions, while hopefully keeping up with the security fixes and other improvements to the engine going in mainline.
