Linux Firefox 1.5b1 render a different font on this site than when Firefox 1.0.6
is used. The 1.0.6 font is better looking and i think that was the page designer
intention. A comparison screenshot will be added to the bug.

Reproducible: Always

Comparing font rendering with 1.0.6 and 1.5b1

This was taken using the original Firefox releases from Mozilla.org, in order
to no compare custom Firefox from the Linux distribution with Firefox 1.5b1.
Running on Fedora Core 4

Go to http://members.ij.net/mrmazda/auth/dpi-screen-window.html and see if both report the same DPI.

I saw this on a Red Hat system the other day after upgrading from 1.0.7 to 1.5.
Ever confirmed: true

Looks to me like your 1.5 profile's default sans-serif font is Nimbus Sans L, and your 1.0.6 profile's default sans-serif font is Bitstream Vera Sans. Vera is considerably larger for any given nominal size than Nimbus. Vera @ 16px is about the same size as Nimbus @ 18px.

Both version was tested using a nre profile, so it is using default font mappings. I found another font rendering problem:

When no lang attribute is used Japanese characters are shown with a different font, one that is not scalable. when using the attribute, the rigth font is used. That never happened on Firefox 1.0.x. See the attached files

Changing version to 1.8 branch because it exists on released Firefox 1.5
Version: Trunk → 1.8 Branch
Does this bug occur in a recent trunk build?
Product: Core → Core Graveyard
Both test cases render identically for me with FF8.  Closing.
