Facebook not working on Safari
Recently, I have been unable to launch some webpages on my preferred browser, Safari. Especially annoying is not being able to launch Facebook. I also (ironically) also have troubles with loading the discussions forum, so I had to use chrome for this. I don't have any problems with other browsers than Safari.
My computer is a Macbook 13 " early 2011 model, running El Capitan 10.11.5, with 8 GB of memory and 2,7 GhZ processor, Intel i7. Don't know if this helps in the diagnostic process. I cannot remember having changed anything drastic on my computer recently, even though I do think that the problems occurred just after I had downloaded NetNanny, a program to block certain websites (but not facebook!). I have uninstalled netnanny, but the problem persists. I have also tried to delete temporary internet data and cookies without success.
The safari browser on my ipad and iphone works fine, no problems there.
any helpful words would be greatly appreciated.
MacBook Pro, OS X El Capitan (10.11.5)
