This bookmarklet will take PG's essay footnotes and make them available to you upon hover over the footnote inline so you don't have to lose your place. To add to Chrome or other browsers, simply create a new bookmark but add the above string as the URL. Then when reading a PG essay, click the bookmarklet and enjoy.

Thanks for making this @vnorby! I modded this to directly embed the footnote into the text for audio text to speech.
