Mozilla Firefox and Thunderbird are using properly "Tahoma" fonts on new systems and "MS Sans Serif" on old Win9x systems but installer fonts are broken. Though installer should use the same UI fonts as the XPGUI applications. Reproducible: Always Steps to Reproduce: 1.Use the firefox / thunderbird setup Actual Results: See ugly unaliased MS Sans Serif fonts on LCD screen on parts of the interface. Expected Results: See aliased Tahoma font.

IMO all UI should use Tahoma on W2k or newer Windows OS.

Isn't this fixed with the new NSIS-based installer?
