Sorry if this is a question, but does anyone know how to install the latest Firefox ESR on Windows Vista?

[RobRoblox]

Before sending your suggestion

• My version of Firefox is up to date (for 115, this means being on at least 115.16.1)
• My copy of Geckium is up to date (no update option in the hamburger/spanner menu)

What browser are you running Geckium on?

Mozilla Firefox

What Operating System are you running Geckium on?

Windows Vista Business

What would you like to suggest for Geckium?

I'm having trouble because I can't watch Facebook videos unless I update to the latest version.

Consider the Vista Extended Kernel project.
Firefox may have some rendering issues, but it's your best bet... besides, well, the obvious other solutions:

• Upgrading Windows
• Switching to a Linux Distro with KDE Plasma, e.g.: Kubuntu 24.10+, and using vistathemeplasma on it

I have an extended kernel installed, but I can only install up to version 118.
