Since the most recent update, I am finding that Firefox has become highly unresponsive when it comes to loading some pages. Some are fine but others such as Reddit and Wikipedia will not or only partially load. Pictures will often only half load or not at all. News articles will often print text and fonts but nothing else. This not occurring on all sites. And it doesn't seem to matter whether the site is https activated or not as some of the other threads seem to indicate is the problem. I need a solution to this.
