Firefox pdf viewer garbles embedded text on some of our pdfs (on Mac OS Mavericks). They're fine in Safari or when downloaded. This is a major problem.

Firefox pdf viewer messes up text on pdfs and makes them unreadable. These fonts are embedded, so there shouldn't be a problem. The pdfs are fine when viewed in Safari or Chrome browsers. Also fine when viewed through Acrobat. Telling me to change my default browser isn't good enough. Visitors to our web site won't know this.

The viewer is a work in progress, and I'm not sure we have any solutions for websites, mostly workarounds for users.

How do you author your PDFs? Can you link to one of them?
