1. What happens if you disable that extension?
2. Does it have any options you can set to reduce the flickering and have the links work?
I just get the impression that it doesn't work optimally with the current release of Firefox and the current version of Google. Such happens. Now wait for the author to release version 0.78.2 or higher.
I have OptimizeGoogle 0.78.1 installed on my Firefox browser (3.6.10 version). Lately, when I call up a result page on Google Search, the page flickers and when I click on a link nothing happens. Anyone else having the same problem? If so, what did you do to correct the problem. BTW, I've used OptimizeGoogle before and this never happened.
