An option is to enable 'Studies' and wait 6 hours until you receive the fix.

Another option seems to download & install the fix xpi manually.
Studies seem to get fetched from https://normandy.cdn.mozilla.net/api/v1/recipe/

And there you have a link to the fix:

Download & install. Everything fixed!
