Mozilla Firefox 116.0 to current Firefox Release and Firefox 128 ESR requires Windows 10, 11 to run.

Firefox 115 ESR, currently at Fx 115.19.0esr is the most current Firefox you can run on the eol Windows, 7, 8, 8.1. The Firefox 115.21.0esr in March is the last planned update unless Mozilla decides soon to extend updates again. https://support.mozilla.org/en-US/kb/firefox-users-windows-7-8-and-81-moving-extended-support

If you mean making builds of current Firefox Release or Fx 128 ESR run on the eol Windows 7, 8, 8.1, well there are no plans for that as it would take people and resources that Mozilla would rather use for Firefox on current OS's.

At least be glad Mozilla is still supporting the eol Windpws, 7, 8, 8.1 as is with Firefox 115 ESR as Chrome/Chromium based browsers dropped Windows 7, 8, 8.1 support back in Jan/Feb 2023.
