Firefox 48.0.2, Windows 7
Ghostery
8.0.5.1 - doesn't work
8.0.4.4 - doesn't work
8.0.3.1 - works

After installing a new version, the Ghostery icon is not active. After clicking on it nothing happens - the Ghostery window is not displayed.
Does this mean that you have stopped supporting older versions of Firefox?

Хорошее дополнение для блокировки рекламы и всяких жучков.

Zeer goed!

So far this extension has been working very good. I have not noticed any changes in the speed of pages loading. Very informative as well. I am liking this extension more and more!!!

GooD

yes

This add-on is amazing. It protects me from so many trackers, and I love how you can click on it and see how many trackers websites are trying to get by

нормальное

Very good Add on. Blocks ads and it's "pause" function works really well for sites that sometimes can't work when the addon is enabled (like Yahoo! mail's search function i.e).
I used to have an adblocker, cookie deleter and a scriptblocker and both have been replaced by Ghostery.

I love it
