When I use Safari 5.0.6 on my MacBook running Mac OS X 10.5.8, various websites will not load. Some will load fine, like the home page of New York Times. However, if I select an article, it won't load. If I try to load google search, it may take several minutes to come up. my.yahoo page will NOT load forever and ever. When I state that it 'doesn't load' I mean that you'll see the address in the address bar and halfway thru that will be a blue progress bar. It just sits there like that and doesn't ever finish loading. If I try the same pages on Firefox, I have no problems at all. I have run the ClamXAV to make sure it's not a virus and it found nothing. I'm not sure what's going on. I have tried resetting Safari and clearing the cache and whatnot, but it made no difference. I tried allowing pop-ups. No change. This has been going on awhile and it's just irritating. Any suggestions?
While your suggestions regarding the '?' safari icon were great, they sadly did NOT fix my issue. With websites not opening. After trying ALL the many suggestions, even Firefox began to act awful. I was at the point where I thought I was going to call in an expert - aka pay someone. However, tonight, I decided to give it another GO. First I googled more and found something about adding a new Location. This did not work at all.
Then I started looking at all the many settings in System Preferences - Network and given that I'm in software/technical support (on Windows and Unix), the IPv6 setting caught my eye. I have had a TON of issues with this recently. I noted that on my MacBook, Configure IPv6 was set to Automatically. I hit the dropdown and noted that my only other option was Off. I threw caution to the wind and I chose OFF and guess what...................
Yep, that fixed it!!! Now everything is peachy. So the solution to my original problem, which is that many common webpages would not open on in Safari (and later began to hang in Firefox, too), was to disable IPv6.
WHY was this a problem? I don't know. I'll google it but wanted to add my solution here for others. Thank you for ALL YOUR TIME!
