Version 2.1.2 is a huge improvement over 2.1.1, but it still interfere with Firefox performance. For instance, it is interfering with one of my extensions that adds an image to a particular web page. When Ghostery is enabled, it takes some time before my extension can append the child element. When I disable Ghostery, the image appears immediately. I still need to review my code to see if there is any bug or if it needs optimization, but considering the previous problems of Ghostery 2.1.1, I would check if it is interfering with other extensions that append elements to web pages.This review is for a previous version of the add-on (2.1.2).
hi lovinglinux! Thanks for using Ghostery. We're aware of the issues in the v2.1 branch and have plugged the known bugs in the next minor release: Ghostery v2.2. Its not ready for public consumption yet, but if you wish to test it, please email me at email@example.com and I will send you a copy.
v2.2 comes with a bug fix that ignores attached elements that are served by the origin domain -- exactly the case you a describing. Additionally, one of the new features is domain whitelisting that would enable you to fully "trust" a domain disabling Ghostery scanning on it.
