I think the issue is that the firefox snap is not able to find substitutes for the default pdf fonts when they are not embedded in the document. PDF documents with embedded fonts render fine with the snap.

Many pdfs have messed-up fonts on this firefox. Following a reddit thread, I tried disabling browser.display.use_document_fonts in about:config. Then the pdfs render correctly, but html webpages have messed-up fonts. Reddit post with screenshots and sample URL here; previous reddit thread linked therein. https://www.reddit.com/r/firefox/comments/uhz6d1/continued_messedup_font_rendering_in_firefox_pdf/ Others (on this and previous thread) report it doesn't happen on other platforms. On this thread, someone confirms it on a Ubuntu VM, and someone else says it doesn't happen on Mint (based on Ubuntu but I think doesn't use snaps).
