Firefox can not read files from ftp sites obtained from an http site

[mexlinux]

Binary package hint: firefox

I'm on Hardy with FF3 (Gecko/2008061015 Firefox/3.)

I'm visiting the Mexican IRS website, it has a lot of links to pdf files stored on an ftp site, I can not read those files from within firefox (I must use nautilus in order to browse for those files)

How to reproduce:
-Go to http://www.sat.gob.mx
-On the left menu click on "Software y formas fiscales"
-Then click on "Formas y formatos fiscales"
-Scroll down and you will see links to some pdf files
-Click on any of those.
-Voila

Thank you for your bugreport. Since this seems to be an issue with
version 3 of the firefox browser, I'm reassigning the package.

 Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.
