Uninstalled Rated 1 out of 5 stars
I updated my Gmail to the new look (the 'Preview' theme) and, lo and behold, I ended with a big 'WebMail Ad Blocker' item in the menu bar, pushing for a donation. As there seemed to be no way to make it disappear, I uninstalled the addon. It might have been useful, but this was intrusion of the most unwelcome kind. I see no difference after uninstall.This review is for a previous version of the add-on (3.3.8).
