With windows7, HTML, CSS3 and JavaScript synchronize them with the latest version of Firefox

[Beast]

Regarding Firefox’s support for Windows 7, I wonder if you will continue to update the versions of HTML, CSS3 and JavaScript to synchronize them with the latest version of Firefox?

I am a network worker, and I design websites for state-owned enterprises(SOEs). Since their operating systems are all Windows 7, displaying correct website content relies heavily on a browser that can correctly display HTML, CSS, and JavaScript. Request Firefox to synchronize the Windows 7 version with the Windows 10 and 11 version updates.

I found that some important css3 properties and selectors, such as has(), cannot be used in version 115.

The extension request can be maintained until at least the end of 2026, because there are still many people using Windows 7 If possible, please continue to update and synchronize the versions and corrections of html/css3/javascript.
