Is this intentional on the part of websites? Perhaps, they are trying to push us into using more traceable browsers like Chrome. Vanilla Firefox may not be the best browser, but Firefox, because it's open-source and has so many security-based plugins from so many different people, Firefox is just about the most secure browser you can use that you can have at least some relative assurance that its code isn't intentionally infected with NSA backdoors. All of the other browsers are either proprietary, like Chrome, or they don't have sufficient plugins to really secure it properly. I think this is something the Firefox creators need to look into because I'm not having these problems on just one of my computers. Every computer I use Firefox on, I'm having increasingly frequent issues signing in to a news site to make comments, watching videos, loading webpages. There very well could be a hidden concentrated effort here to cause people to use a different browser from Firefox by having left-loyal webmasters intentionally input code to cause problems with those who are using Firefox. This sort of underhanded thing would not be beneath liberals or Democrats. Look at how they treated Palin, how they are not attacking Dr. Carson, how they treated Bush. There's no level to which the left will not sink. If it can be feasibly done and it would actually produce a desired affect, such as getting people to switch browsers to a proprietary browser that is more NSA-friendly, they will do it.
