Font on entire page is replaced with A in boxes

A link took me to Apple's website where every letter on the page was replaced by an A in a box. I was able to copy the page by highlighting it and then pasting it into TextEdit to see everything, so it knows what the text is. Any suggestions?

Thanks much!

    Yes, this is a bad font ATSUI can't render. These have to be manually blacklisted. We will update the list for FPR2.

    Then you're going to have to blacklist Apple's website. Support pages (e.g., and Apple ID management page (i.e., have this problem as well, as of about 4:00 p.m. EDT on July 10.

    I have to access these pages, the latter to log in and make account changes so I can access my e-mail. Banning the page is not going to help me. This is my only computer.

    We're crazy, but we're not that crazy.

    The font is blacklisted, not the page. The browser will select a fallback from the fonts the page specifies or available fonts on your system. The font blacklist has been a part of TenFourFox since version 17 to work around bugs in the 10.4 SDK and ATSUI.

    (Meanwhile, if you can't wait for the FPR2 beta, you can temporarily turn off downloadable fonts to view the page by setting gfx.downloadable_fonts.enabled to false in about:config and then reloading the page. Make sure you turn the setting back to true when you are done, as it inhibits downloadable fonts on all pages, not just Apple's.)

    Changed the setting and attempted to reload the page at

    The overlay for member sign-in does not load.

    It typically takes a while to come up, often with a slow JavaScript error, but it eventually loads.

    I guess I'll have to wait for a new version of TenFourFox before I make the changes to my account.
