This is a fairly serious bug that affects so many websites with uncommon fonts, most notably Google services like Gmail using the Roboto font. Refreshing the page has a chance of loading the missing symbols but it's not guaranteed.

However, when selecting all (CTRL-a) and copying the text to an text editor, the proper text is available. Therefore, the text is not rendered or using an strange font without any glyphs in it. I repeated this with the usually not used "Guest Account". Hence it is not an issue with my personal setting. The issue appeared when upgrading to Ubuntu Zesty (17.04). The current Firefox package install is 52.0+build2-0ubuntu0.16.10.1 I will downgrade not to 50.1.0+build2-0ubuntu1 to reexamine the issue.
