I'm having this exact same problem in Safari. Have followed the directions here from Linc Davis. Was able to find and remove the vsearch files, but not the ones with the word "jack" in them (listed above).
NOTE: I don't appear to get this problem in Safari, which I've had to switch to. Then again, I never use Safari unless Firefox isn't working for a specific task.
Here are the results from the diagnostic Linc suggested above. Any help would be greatly appreciated. I can already see I've got the Genie adware still running, though I've tried several times to get rid of it.
Boot Mode: Normal
Model: MacBookPro9,1
