downloadable font: format not supported

[ishikawa]

While I was checking some strange behavior of accessing google apps
from firefox (firefox v 9.0.1 under windows XP),
I noticed a series of errors that have something to do with donloadable font.

One typical sequence of messages in error console is shown below.
(I edited the "warning:", "source file:", "line:", etc. to avoid
inserting Japanese characters in the posting. When I copy the messages from
the error console, these legends are shown in Japanese names on my computer.)

The initial warning message and firefox's internal error handling seems to
result in the error message that follows.

(There are many more about different fonts.)

I have no idea what is wrong.
I found a few references about cross-domain font downloading which seemed to
fail under a few conditions. But I am not sure if this is the case with the
particular error messages above.

Can anyone shed any light on this matter?

TIA

(I have found a few compatibility issues when I use firefox with Google
Apps, and now trying to figure out what is wrong.
Google seems to insist that its users are best served when they use Chrome,
oh well.)

For Windows OS's, valid fonts are of format *.TTF or *.OTF, so the errors
You saw are correctly informing You that the fonts the site is attempting
to download are invalid. If I remember correctly, the *.eof format is am
out of date MS technology which used there WEFT tool to generate font
extracts useable by some MS Office products 8-10 years ago.

A correction: The format is *.eot.

Thank you for the enlightment.

Now, it is time to figure out why my browser is asked to
download invalid font. (Maybe google aps asked for it?)
