Recently read about a Gmail plugin that enables someone sending me email to tell whether I opened an email or not, without my knowledge.
See article here: http://www.huffingtonpost.com/2014/02/12/streak-gmail_n_4774889.html
One of article comments suggested that this plugin could be made non-functional on my side with Adblock Plus. However, the plugin doesn't present anything on my screen that I can detect and click on to add a filter. So, two questions:
- Can that Gmail Chrome plugin be disabled using Adblock Plus? (not sure if Streak works on other browsers)
- How do I add a filter manually when I do not know the structure of the URL (since I can't see it)?
Generally it may be helpful to develop some capability to detect, and add to filters, stealth plugins like this one. I assume there will be more...
