Mozilla announced in a press release that will 2017 stop support internet browser Firefox operating system Microsoft Windows XP si Windows Vista.
"We expect to continue to provide security updates for [Windows XP and Windows Vista] users until September 2017,"
It is not known for sure how many users in the world still use the operating system on computers Windows XP, but definitely Windows Vista is almost non-existent, being the worst / worst operating system ever created in Microsoft history.
There are statistical companies, which have estimated a maximum of 4% computers with Windows XP and less than 1% running Vista. These were the figures for mid-2016, but until the summer or fall of 2017, when Mozilla withdraws support for Firefox, it is very possible that Windows Vista to be almost non-existent on PCs in the world.
Cu Windows XP, is a slightly more delicate issue. Although it is an older system than it is Windows Vista, XP was the operating system that made history, being used on a very large scale for many years. Public, research and educational institutions still use PCs Windows XP. To support them, Mozilla will release in March 2017, a version Firefox Extended Support Release (ESR).
ESR will be a Firefox will still cost Security updates (As long as the operating system and architecture) but will not benefit from new features and innovations. It will be a simple browsing version, without too much claim, but enough for institutions. This ESR version will remain in operation for about a year. This practice was also adopted by Microsoft with the program: Windows 10 Long Term Servicing Branch (LTSB).
With this announcement, Mozilla encourages users to use the latest versions of Windows go to Microsoft.
"We strongly encourage our users to upgrade to a version of Windows that is supported by Microsoft"
Even if sometimes we are more conservative, we must recognize that technology is evolving a lot, and quite quickly, and to keep up with it, is often a necessity.
