firefox won't show .pdfs properly

Ray Andrews

Firefox screws up showing .pdfs. The first view is fine but scrolling seems to overprint the first view without erasing it, if that makes sense, sorta like a double exposure. I can't get a screen cap either, which might just mean it's not a firefox issue at all, but I can view and screen cap .pdfs from any other application. I'm running Debian 12 up to date. When I need to view a .pdf I use Chromium, but I do prefer Firefox.

It looks fine, but that's because I've switched to the other viewer. Tomorrow I'll switch back to the default and see if I can screen cap. But as I said, I had trouble with screen cap too which seems strange and made me suspect a wider issue.

BTW this has been going on for quite some time, I thought it might shake itself out after an upgrade or two, but it hasn't.

Following another question, I changed the default viewer to atril and that works fine. So it does seem that there's a bug in the default viewer.

Issue resolved? If so, mark it as resolved and have a nice day.

Half resolved. The default viewer is busted it seems. If there's no alternative but to switch viewers then should this be reported as a bug? If the devs are interested.

Show us something. Provide steps to replicate if needed. What happens on this site? --> https://www.irs.gov/downloads/irs-pdf

Well I dunno. Now everything is fine even if I go back to the old settings. I'll resurrect this question if the problem reappears.

Won't render with FF nor if I select 'atril' as the viewer. However if I save the page to disk, I can view it with atril just fine.
