    I’m curious, have you tried SumatraPDF (uses muPDF under the hood)?

    Do you mind reporting those issues either to SumatraPDF at https://github.com/sumatrapdfreader/sumatrapdf/issues or directly to MuPDF at https://bugs.ghostscript.com/ if it also has the same issue? Thank you!

    There are many wonderfully weird PDFs and epubs out there, but we do our best to fix issues. :)

    FWIW, https://github.com/sumatrapdfreader/sumatrapdf/issues/1249 ("Support form filling for at least 1040 irs form") has a comment saying "MuPDF-GL has the capability to edit fields and save the PDF" of a 1040.

    I have just learned the Firefox 93 added support XFA - https://techdows.com/2021/10/open-xfa-pdfs-in-firefox.html .

    So it would appear there are free software solutions to XFA forms.

    Just because something doesn't seem far-fetched to you, doesn't mean most people will regard it as far-fetched.

    Many people all sorts of "sectarian objections" - far more than there are SovCits or other tax protesters. Stallman has never come across as a tax protester. Ergo, I think it's far-fetched that "sectarian objections" is strongly associated with tax protests.

    Further, at https://stallman.org/archives/2017-may-aug.html we can read Stallman opinine that we need to "return to the "bad old days", when Americans in general could have a decent life, not penury; when the US could afford to build what the public needed instead of privatizing everything with a toll" by making taxation more progressive. At https://stallman.org/archives/2011-jan-apr.html we read he supports "The Fairness in Taxation Act [which] would raise taxes to 45% on incomes over a million dollars a year."

    If you are going to run something in wine, try sumatrapdf. It's FOSS but Windows only. (sadly, but runs great on wine)

    Sumatra PDF has always been my choice: minimal, lightweight, no bloat... just perfect!

    But not just off-topic: abusive, and dishonest.

    I'm not sure this even applies as we call the mutool binary installed via apt, rather than use or modify their libraries.

    Even if it applies, Mu's AGPL requires you release the source code, which is what we already and have always done. So it doesn't apply. It doesn't require you use a particular license.

    As you're so keen on searching our source you could have also easily read what the AGPL means, and seen that we use mutool^0, which I guess you would have done, if you were actually intending to be helpful rather than just trying to make us look bad, right? Hahaha! :)

    I guess you're one of those people bitter at our success or maybe you were trying to use BrowserBox without paying the licensing fees and you didn't like that we made it commercial, is that right? Hahaha! :)

    It seems if you were genuinely trying to be helpful rather than dishonest and trying to make us look bad, you would have just emailed me, right? Hahahahaha! :)

    If you're interested in this kind of thing, I packaged a lot of functionality (including zip files) into an open source doc viewer called "chai" (that also works on mac, install deps via brew).

    Please note its focus is on security rather than looks so it converts docs to page images that you then view in (an optionally local) web client.

    You can easily modify the convert process to move it to PDF rather than page images tho. Check it out: https://github.com/dosyago/chai
