This Ghostery extension disfigures *every* web page for 10 seconds with a bright purple display in the lower right corner of the web page showing all the trackers it has blocked.
Yes, bright purple junk added to *every* web page for 10 seconds.
Highly distracting and unacceptable for any extension to add spam to web pages.
This extension *must* be changed (in order to not consider it being spam itself) to have an option to allow not showing that purple non-static (hence distracting) spam for 10 seconds on every web page.
Obviously I am uninstalling this spamware now, after incorrectly blaming the problem on the newest version 69 of Firefox (which btw actually recommended this Ghostery extension).
