Whenever I go to some websites there are a few that come up with: "Unable to connect Firefox can't establish a connection to the server.." and the problem occurs with the same websites on other browsers. What might be the problem?

If you get the same problems with two browsers, the problem is outside of them. Check you computer for blocking programs.

Separate Issue; Your System Details shows;

Installed Plug-ins

Shockwave Flash 15.0 r0 Shockwave Flash 16.0 r0

Having more than one version of a program may cause issues.

Grab the uninstaller from here: Uninstall Flash Player | Windows Uninstall Flash Player | Mac Then reinstall the latest version.

Flash Player v16.0.0.257 https://www.adobe.com/products/flashplayer/distribution3.html
