Yes, this fix worked for many of my applications, including yahoo messenger, which used to be bolded all the time and youtube.
However, the wikipedia page has been drastically changed. The font is almost unreadable, and close together. I repeated your fix several times, but still no change. My yahoo mail font has changed, but i can bear with it, as the font is readable.
Please help me with my problem, I practically worship wikipedia, on a daily basis
