Fonts are still bolder in Mac version only

I've searched like crazy online, found this happening for some throughout many different versions, but still find no solution.

On the latest version (v23) and a few previous now, we're seeing fonts which are more bold than on any other browser. This includes text and our font icons.

Strangely, and beyond us, we have one guy here on the same FF and OSX versions who does not have this problem. We can't figure out why.

FF on Win does not have this problem.

The hardware acceleration feature can affect font weight. If you toggle it off, does that have any effect?

Firefox menu > Preferences > Advanced

On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"

You generally need to restart Firefox for this change to take effect.

Thanks, but this is one of the things I've tried. Tried again, still an issue.

Could be caused by the kind of anti-aliasing or font hinting that is used on Mac.

Well, the odd thing is we have one person here who does not see this issue at all, so it seems related to something on the browser side... perhaps a plug in or setting.

Seems more on the browser side than the CSS side.
