It has only stated today after installing KDE's system settings and configuring it to make KDE apps look native . Firefox has started using a thinner font.
so how do i make it use the default fonts ?

What you are seeing is font hinting.
First, play with the font rendering settings in KDE and see if it fixes your problem.
You can probably disable it in about:config by searching for the preferences starting with "gfx" and testing them out.
All font settings are stored in a hidden file in your home folder, called .fonts.conf.
If you remove it (in your home folder, press Ctrl + H, and delete .fonts.conf), and generate a new one, by running, in a terminal instance (Applications > Accessories > Terminal):
sudo dpkg-reconfigure fontconfig
You then should get the usual Linux crystal clear fonts (you actually may need to log out and log back in, but that's it)
