Why are my fonts bold in both Chromium and Firefox?

(I have not modified any font settings in Chromium or Firefox; this is a fresh install.)

I can confirm I also have this problem, but also with Elementary OS (which is based off of 10.10). – Ethan Turkeltaub Jun 6 '11 at 21:27

This is likely a problem with manual installation of fonts. Install MS fonts from ttf-mscorefonts-installer package to ensure all font files are installed, and if you installed these fonts manually, remove them from your personal fonts folder (~/.fonts).

On Chrome go to Preferences>Advanced>Web Content , you will be presented with the respective options to change them. Chrome

I don't know 'bout Firefox though.

It's not an issue with either of the browsers, it's an issue with Ubuntu. (I didn't modify any browser settings, and they're not like this on older versions of Ubuntu.) – Mehrdad May 21 '11 at 0:22
make sure that the fonts on the browsers match the fonts you're using with ubuntu – Uri Herrera May 21 '11 at 0:25
Irrespective of what other pages look like, the Settings page of Chromium itself has this problem. (I'm referring to the exact screenshot that you have: it's bold in my installation.) That's not something I can change from within Chromium. – Mehrdad May 21 '11 at 1:02
Setting a different font than Segoe has the same problem? – David Rando May 21 '11 at 2:46

I see this thread is almost two years old but I'm posting my workaround for others to use:

I had the same exact problem with Chrome on Ubuntu 12.10. I installed the Roboto font in ~/.fonts (all 16 fonts). Even though I set everything to "Roboto Light" under gnome-tweak-tool, Chrome was still using Black (or Bold).

To fix it: I deleted all Roboto fonts except for the Light variant and it started to work properly. Perhaps you should try this, removing the other variants of

Still unsure why Chrome did this, but perhaps it just sees "Roboto" has the font and picks the first file in the folder?

Deleting fonts is not the ideal solution, but thank you for sharing the option :-) – Sander Steffann Jan 25 '13 at 10:17

For me the solution for bold fonts in Google Chrome was

rm -rf /usr/share/fonts/truetype/roboto

I've installed the Roboto fonts myself a long time ago. The location should be the same if you haven't copied it manually. I'm using Mint 17.
