Notes from the maintainer:

Figma currently only requests local fonts on Windows and macOS. They also chose a different port for the service. (18412 -> 44950)

Please upgrade to version 0.3.2 for the port changes. However, we still need to override the browser's user-agent. There is nothing I can do about it.

The issue report on the Figma's official forum: https://forum.figma.com/t/requests-to-font-helper-on-linux-stopped-working/61389

I'm having the same issue. I tested in Chromium and Firefox and in both cases Figma doesn't seem to even be making any request to the agent like in https://github.com/neetly/figma-agent-linux/issues/134#issuecomment-1868670410. I tried the cURL command and it returned a JSON with all fonts I've installed.

I discovered that Figma only queries the font agent if it is running on an officially supported operating system, i.e. Windows and macOS. Since there's no official client for Linux, it skips the HTTP request. Changing my browser's user agent to a supported OS was enough to bypass this check. I also had to change the port in figma-agent.socket to 44950. After that my local fonts appeared.

Thanks! @m4theushw It worked for me as well.

I changed the browser agent to windows and set port ( ListenStream ) to 44950

nano .config/systemd/user/sockets.target.wants/figma-agent.socket

And it worked after restarting the socket and service.

Let me keep this issue open for tracking purposes.

Same issue for me as well. Changing port and user agent string worked. Oddly, changing it to Chrome-Macos as the user agent didn't work, Chrome-Windows as the user agent did though.

Figma Agent stopped working after Chrome update

I'm on Fedora and today (May 11th) I updated my Chrome to 124.0.6367.201, after that my local fonts stopped working. It was tested on both the Flatpak and the RPM package. I know the problem is on Chrome's side since it works on Firefox. Reporting here in case someone also finds themselves with the problem.

Here is the user-agent: User Agent
