Hi, we have a web application that runs Silverlight so i was just wondering how long Firefox 52 ESR will be available to download? Is this information you could provide?

also if we have a link to a download of Firefox ESR 52 will that stop working when you take out the download links on your website?

Thank you

Firefox 52 will be supported approximately another month. It should not be used on the internet after then, as it will be vulnerable to known and unpatched security vulnerabilities, as well as be over a year behind current web technology.
