Figma Linux Font Helper
Figma can access local fonts on your computer. Except if you are using Linux.
There's this Font Helper that overcomes this limitation, but I was reticent to install it on my Ubuntu. Only because it adds a system service, and I just did not want to go through the trouble of uninstalling and cleaning in case it did not work on my system.
While searching yet again for a solution, I discovered the Figma Linux Font Helper! Yes, it has the same name, and it also takes a similar approach to solving the limitation. The good news is, it doesn't require any installation because it works with... Docker.
