Experienced Behavior

not working yet in visual code, trying to use with: gh-dash

I've tried just about every combination I can think of in the font section:

Menlo, Monaco, 'Courier New', monospace, 'Fira Code NFM'
Menlo, Monaco, 'Courier New', monospace, 'Fira Code NF'
Menlo, Monaco, 'Courier New', monospace, 'Fira Code Nerd Font'
Menlo, Monaco, 'Courier New', monospace, 'Fira Code Nerd Font Mono'
Menlo, Monaco, 'Courier New', monospace, 'FiraCode NFM'
Menlo, Monaco, 'Courier New', monospace, 'FiraCode NF'
Menlo, Monaco, 'Courier New', monospace, 'FiraCode Nerd Font'
Menlo, Monaco, 'Courier New', monospace, 'FiraCode Nerd Font Mono'

I've also tried the steps at this location:

Source of Font File

also tried from the FiraCode release page:

Terminal Emulator (and the title of the terminal window)

VisualStudioCode

Operating System and Version

MacBook Pro, Sequoia 15.5

The report provides a Visual Studio Code settings snippet and lists the installed FiraCodeNerdFont files, but names no repository files or tests. Start by reproducing the font-family configuration on macOS Sequoia and checking whether Visual Studio Code recognizes the installed family; done would require a confirmed cause and a clearly documented fix.
