I checked that...

• ... the documentation does not mention anything about my problem
• ... the problem doesn't occur with the default MkDocs template
• ... the problem is not in any of my customizations (CSS, JS, template)
• ... there are no open or closed issues that are related to my problem

Description

The return link is only shown, when the footnote is hovered or targeted, otherwise it is hidden. I don't know exactly how the PDF plugin works, but if it uses print styles, we could - in theory - display it. Are the other anchors clickable in the PDF? I never tried the export plugin.

Also note that this plugin adds custom CSS before printing:

As the plugin already customizes the CSS, please open an issue over at the plugin repository.

It is clickable, just not shown.

Ok, i will open a new issue there, thanks.

As we're currently in the process of refactoring the theme, I checked the print styles and improved some of them in 71b2f5a. This should also fix the footnotes problem you mentioned. This fix will be part of the next major release. See #1498 for progress.
