Well, though Chrome is my preferred browser, I'm switching back to FireFox specifically to block skimlinks. This is really outrageous -- unethical behavior of the lowest sort.

Edited to add:

Done -- I'm on with FF (with, of course, ....... plus). FT is a lot faster and, of course, as a bonus, I don't have to look at any ads. Well done, IBB! We'll simply pass the word around that, because of your undisclosed browser hijacking, the preferred solution involves blocking all of your ads.
