Firefox won't load any websites after updating Mac OSX
I just updated my Mac's OS to El Capitan and now I can't get any websites to load in Firefox. They work fine in Chrome, though I'm also having some problems getting some websites to work in safari. I went through the entire article on the support site and made all the changes, but nothing works. I've also uninstalled and reinstalled firefox and restarted my computer. Still no progress. Any suggestions?

What is your computer system and Firefox?
Type about:preferences#advanced<Enter> in the address bar.
Under Advanced, Select Network. Look for Configure How Firefox Connects and press the Settings button. If you are using a proxy, make sure those settings are correct. If there is no proxy, first use No Proxy. If there is a problem, then try System Proxy.
Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;
- Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
- Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Try to disable IPv6 (check for other possible causes as well).
