I've never used the Microsoft fonts on Linux, so maybe I'm completely misinterpreting your question, but if it's just a case of you wanting to know names of Microsoft fonts:

The classics:

- Times New Roman (Serif)

- Arial (Sans)

- Lucida Console (Mono)

ClearType fonts:

- Calibri (Sans; the default font in MS Office 2007 onwards)

- Constantia (Serif)

- Corbel (Sans)

- Cambria (Serif)

- Candara (Sans)

- Consolas (Mono)

And then they also use the Segoe family of fonts a lot in the Windows UI.

As for what (non-Microsoft) font I use, this one: https://mozilla.github.io/Fira/ (Sans and Mono)

Thanks for your response. But I should have phrased my question better. I'm actually trying to reproduce the fonts Chrome uses, on my Firefox on Ubuntu.

Webfonts, when not blocked by any of the privacy protection add ons I use, or DejaVu 16 for Sans and Serif and DejaVu 12 for Mono.

What font do you use and why this question?

I'm currently using the default DejaVu fonts.

I used Firefox earlier and jumped on the Chrome bandwagon when it became popular. I just made a switch back from Chrome to Firefox and it feels a lot faster than Chrome.

I have installed Microsoft fonts on my Ubuntu and Chrome uses these fonts. Now, I'm trying to make Firefox use the same fonts but I don't seem to figure out the font names for Serif, Sans-serif, and Monospace.

I'll add these details to my question.

The DejaVu font family has a DejaVu Sans, a DejaVu Serif and a DejaVu Mono. You should see them listed in Settings, Font, in the font selector of LibreOffice Writer and obviously in Firefox, where you pick a font in the settings.

dpkg -l tells me that I've got installed fonts-dejavu, fonts-dejavu-core and fonts-dejavu-extra.
