What year is your Mac?
Unfortunately, you're going to have problems with websites on Safari on a Mac running v10.7.5 Lion.
The alternative is to use the Firefox Web Browser
Minimum requirements for Firefox is v10.6 Snow Leopard so it should work fine on your Mac.
Just in case, check to see if your Mac meets v10.11 El Capitan requirements here > Upgrade to OS X El Capitan
use safari to open other websites
