Constantly, however quite sporadically, links or buttons within websites just stop working and go dead: but only when using Mozilla on my windows computer. For instance, I was just on a website for grohe bathroom fixtures. I chose to load 100 products per page. I got to the bottom of the page and want to click on the second of two page possibilities, and nothing happens when I click. This happens all the time, for months and months now! Why are internal links or buttons going dead on various sites, for no reason, no timing I can put my finger on or anything else. The only fix is to reload the page, and when that doesn't work i resort to loading the page on chrome.
