I have groped around in the Webkit source a bit, but all I could find was the build-time ENABLED(PDF) switches – which is not helpful in my case, as I would like to keep using my distribution's packages), and grepping for enable-something in the built libwebkitgtk did not yield anything either. So... can we have a pdf.js-switch? Or could the the pdf.js machinery at least honour the enable-plugins setting? 1971786 1 webkit-bug-importer 2023-08-17 03:34:13 -0700 <rdar://problem/114018319> 1984832 2 berto 2023-10-13 03:10:26 -0700 Also reported downstream in Debian recently for WebKitGTK: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1053713 1984858 3 mcatanzaro 2023-10-13 05:42:13 -0700 There is a PdfJSViewerEnabled setting for this, but it's not exposed for WPE/GTK APIs. This would be a good first pull request for anyone interested in contributing. Add the setting to WebKitSettings.h.in and WebKitSettings.cpp, then add a sanity-check test to TestWebKitSettings.cpp just to ensure that toggling the setting works. Most of the work will be copy/pasting from an existing setting and then renaming things. 1984932 4 mcatanzaro 2023-10-13 10:56:51 -0700 OK, this can sort of be done already using webkit_settings_get_all_features(), iterate through the list until you find PdfJSViewerEnabled, and then webkit_settings_set_feature_enabled(). That's not very convenient, though. 2190520 5 berto 2026-03-16 03:17:24 -0700 Another related request is whether WebKit can be built to use pdf.js as provided by the distro instead of bundling its own copy inside the binary: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1130768 2190572 6 mcatanzaro 2026-03-16 07:37:11 -0700 I don't think that's related to this bug at all.
