Hello Jeremy and tb, Thank you both for testing 5.1.10-prerelease on your computers.
The issue is now resolved by disabling both the Firefox pdf plugins and then following the instructions under this heading "If PDF files are downloaded instead of displayed, try these solutions" at this address https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-without-downloading-them ...And then in Firefox doing: Tools -> Options -> Applications and setting the PDF "Content Type" "Action" to "Preview in Firefox" from the drop-down list @tb, I've no preference for these plugins over the native Firefox rendering, but I probably should have paid more attention when installing the viewer software (Adobe and PDF-XChange) and not allowed them to install Firefox plugins. Hopefully I'll remember next time. Thanks again for your patience and help, Bob -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
