Yes if you use the old Firefox 115 ESR channel. It is currently at 115.33.0esr released on Feb 24.

It was the last planned update for the old Firefox 115 ESR channel however one source I have see very7 recently says they may have decided to extend updates support til August.

Btw you need to fix your UserAgent as the UA you posted this thread is Mozilla/5.0 (Windows NT 5.1; rv:109.0) Gecko/20100101 Firefox/115.0
The NT 5.1 is Windows XP and the last version to support Windows XP was the old Firefox 52.9.0esr. https://support.mozilla.org/en-US/kb/end-support-windows-xp-and-vista
So either you have modified the UA in some way or you are running Firefox in Windows XP compatibility mode for some reason on Windows 7. https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox
Turns out Mozilla decided very recently to extend the updates for the older Firefox 115 ESR yet again until later August 2026 to support the Windows 7, 8, 8.1 and macOS 10.12, 10.13, 10.14 for while longer.
